MS Windows network -administrators are often confused regarding network access controls and how to -provide users with the access they need while protecting resources from unauthorised access. -</p><p> -Many UNIX administrators are unfamiliar with the MS Windows environment and in particular -have difficulty in visualizing what the MS Windows user wishes to achieve in attempts to set file -and directory access permissions. -</p><p> -The problem lies in the differences in how file and directory permissions and controls work -between the two environments. This difference is one that Samba can not completely hide, even -though it does try to bridge the chasm to a degree. -</p><a class="indexterm" name="id2904225"></a><p> -POSIX Access Control List technology has been available (along with Extended Attributes) -for UNIX for many years, yet there is little evidence today of any significant use. This -explains to some extent the slow adoption of ACLs into commercial Linux products. MS Windows -administrators are astounded at this given that ACLs were a foundational capability of the now -decade old MS Windows NT operating system. -</p><p> -The purpose of this chapter is to present each of the points of control that are possible with -Samba-3 in the hope that this will help the network administrator to find the optimum method -for delivering the best environment for MS Windows desktop users. -</p><p> -This is an opportune point to mention that Samba was created to provide a means of interoperability -and interchange of data between differing operating environments. Samba has no intent change -UNIX/Linux into a platform like MS Windows. Instead the purpose was and is to provide a sufficient -level of exchange of data between the two environments. What is available today extends well -beyond early plans and expectations, yet the gap continues to shrink. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2904266"></a>Features and Benefits</h2></div></div><div></div></div><p> - Samba offers a lot of flexibility in file system access management. These are the key access control - facilities present in Samba today: - </p><div class="itemizedlist"><p class="title"><b>Samba Access Control Facilities</b></p><ul type="disc"><li><p> - <span class="emphasis"><em>UNIX File and Directory Permissions</em></span> - </p><p> - Samba honours and implements UNIX file system access controls. Users - who access a Samba server will do so as a particular MS Windows user. - This information is passed to the Samba server as part of the logon or - connection setup process. Samba uses this user identity to validate - whether or not the user should be given access to file system resources - (files and directories). This chapter provides an overview for those - to whom the UNIX permissions and controls are a little strange or unknown. - </p></li><li><p> - <span class="emphasis"><em>Samba Share Definitions</em></span> - </p><p> - In configuring share settings and controls in the <tt class="filename">smb.conf</tt> file - the network administrator can exercise over-rides to native file - system permissions and behaviours. This can be handy and convenient - to affect behaviour that is more like what MS Windows NT users expect - but it is seldom the <span class="emphasis"><em>best</em></span> way to achieve this. - The basic options and techniques are described herein. - </p></li><li><p> - <span class="emphasis"><em>Samba Share ACLs</em></span> - </p><p> - Just like it is possible in MS Windows NT to set ACLs on shares - themselves, so it is possible to do this in Samba. - Very few people make use of this facility, yet it remains on of the - easiest ways to affect access controls (restrictions) and can often - do so with minimum invasiveness compared with other methods. - </p></li><li><p> - <span class="emphasis"><em>MS Windows ACLs through UNIX POSIX ACLs</em></span> - </p><p> - The use of POSIX ACLs on UNIX/Linux is possible ONLY if the underlying - operating system supports them. If not, then this option will not be - available to you. Current UNIX technology platforms have native support - for POSIX ACLs. There are patches for the Linux kernel that provide - this also. Sadly, few Linux platforms ship today with native ACLs and - Extended Attributes enabled. This chapter has pertinent information - for users of platforms that support them. - </p></li></ul></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2904395"></a>File System Access Controls</h2></div></div><div></div></div><p> -Perhaps the most important recognition to be made is the simple fact that MS Windows NT4 / 200x / XP -implement a totally divergent file system technology from what is provided in the UNIX operating system -environment. Firstly we should consider what the most significant differences are, then we shall look -at how Samba helps to bridge the differences. -</p><a class="indexterm" name="id2904414"></a><a class="indexterm" name="id2904423"></a><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2904431"></a>MS Windows NTFS Comparison with UNIX File Systems</h3></div></div><div></div></div><p> - Samba operates on top of the UNIX file system. This means it is subject to UNIX file system conventions - and permissions. It also means that if the MS Windows networking environment requires file system - behaviour that differs from unix file system behaviour then somehow Samba is responsible for emulating - that in a transparent and consistent manner. - </p><p> - It is good news that Samba does this to a very large extent and on top of that provides a high degree - of optional configuration to over-ride the default behaviour. We will look at some of these over-rides, - but for the greater part we will stay within the bounds of default behaviour. Those wishing to explore - to depths of control ability should review the <tt class="filename">smb.conf</tt> man page. - </p><div class="variablelist"><p class="title"><b>File System Feature Comparison</b></p><dl><dt><span class="term">Name Space</span></dt><dd><p> - MS Windows NT4 / 200x/ XP files names may be up to 254 characters long, UNIX file names - may be 1023 characters long. In MS Windows file extensions indicate particular file types, - in UNIX this is not so rigorously observed as all names are considered arbitrary. - </p><p> - What MS Windows calls a Folder, UNIX calls a directory. - </p></dd><dt><span class="term">Case Sensitivity</span></dt><dd><p> - <a class="indexterm" name="id2904517"></a> - MS Windows file names are generally upper case if made up of 8.3 (ie: 8 character file name - and 3 character extension. If longer than 8.3 file names are Case Preserving, and Case - Insensitive. - </p><p> - UNIX file and directory names are case sensitive and case preserving. Samba implements the - MS Windows file name behaviour, but it does so as a user application. The UNIX file system - provides no mechanism to perform case insensitive file name lookups. MS Windows does this - by default. This means that Samba has to carry the processing overhead to provide features - that are NOT native to the UNIX operating system environment. - </p><p> - Consider the following, all are unique UNIX names but one single MS Windows file name: - <tt class="computeroutput"> - MYFILE.TXT - MyFile.txt - myfile.txt - </tt> - So clearly, In an MS Windows file name space these three files CAN NOT co-exist! But in UNIX - they can. So what should Samba do if all three are present? Answer, the one that is lexically - first will be accessible to MS Windows users, the others are invisible and unaccessible - any - other solution would be suicidal. - </p></dd><dt><span class="term">Directory Separators</span></dt><dd><p> - MS Windows and DOS uses the back-slash '\' as a directory delimiter, UNIX uses the forward-slash '/' - as it's directory delimiter. This is transparently handled by Samba. - </p></dd><dt><span class="term">Drive Identification</span></dt><dd><p> - MS Windows products support a notion of drive letters, like <b class="command">C:</b> to represent - disk partitions. UNIX has NO concept if separate identifiers for file partitions since each - such file system is <tt class="filename">mounted</tt> to become part of the over-all directory tree. - The UNIX directory tree begins at '/', just like the root of a DOS drive is specified like - <b class="command">C:\</b>. - </p></dd><dt><span class="term">File Naming Conventions</span></dt><dd><p> - MS Windows generally never experiences file names that begin with a '.', while in UNIX these - are commonly found in a user's home directory. Files that begin with a '.' are typically - either start up files for various UNIX applications, or they may be files that contain - start-up configuration data. - </p></dd><dt><span class="term">Links and Short-Cuts</span></dt><dd><p> - <a class="indexterm" name="id2904667"></a> - <a class="indexterm" name="id2904678"></a> - <a class="indexterm" name="id2904689"></a> - - MS Windows make use of "links and Short-Cuts" that are actually special types of files that will - redirect an attempt to execute the file to the real location of the file. UNIX knows of file and directory - links, but they are entirely different from what MS Windows users are used to. - </p><p> - Symbolic links are files in UNIX that contain the actual location of the data (file OR directory). An - operation (like read or write) will operate directly on the file referenced. Symbolic links are also - referred to as 'soft links'. A hard link is something that MS Windows is NOT familiar with. It allows - one physical file to be known simultaneously by more than one file name. - </p></dd></dl></div><p> - There are many other subtle differences that may cause the MS Windows administrator some temporary discomfort - in the process of becoming familiar with UNIX/Linux. These are best left for a text that is dedicated to the - purpose of UNIX/Linux training/education. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2904735"></a>Managing Directories</h3></div></div><div></div></div><p> - There are three basic operations for managing directories, <b class="command">create, delete, rename</b>. - </p><div class="table"><a name="id2904754"></a><p class="title"><b>Table 13.1.

This means that you can only - manipulate the current user/group/world permissions listed in - the dialog box. This actually works quite well as these are the - only permissions that UNIX actually has.</p><p>If a permission triplet (either user, group, or world) - is removed from the list of permissions in the NT dialog box, - then when the <span class="guibutton">OK</span> button is pressed it will - be applied as "no permissions" on the UNIX side.

From inside that (remote X) - session I started a rdesktop session on another, a Windows XP machine. - To test the performance, I played Pinball. I am proud to announce here - that my score was 631750 points at first try... - </p><p> - NX performs better on my local LAN than any of the other "pure" - connection methods I am using from time to time: TightVNC, rdesktop or - remote X. It is even faster than a direct crosslink connection between - two nodes. - </p><p> - I even got sound playing from the remote X app to my local boxes, and - had a working "copy'n'paste" from an NX window (running a KDE session - in Italy) to my Mozilla mailing agent... These guys are certainly doing - something right! - </p><p> - I recommend to test drive NX to anybody with a only a remote interest - in remote computing - <a href="http://www.nomachine.com/testdrive.php" target="_top">http://www.nomachine.com/testdrive.php</a>. - </p><p> - Just download the free of charge client software (available for RedHat, - SuSE, Debian and Windows) and be up and running within 5 minutes (they - need to send you your account data, though, because you are assigned - a real Unix account on their testdrive.nomachine.com box... - </p><p> - They plan to get to the point were you can have NX application servers - running as a cluster of nodes, and users simply start an NX session locally, - and can select applications to run transparently (apps may even run on - another NX node, but pretend to be on the same as used for initial login, - because it displays in the same window.... well, you also can run it - fullscreen, and after a short time you forget that it is a remote session - at all). - </p><p> - Now the best thing at the end: all the core compression and caching - technologies are released under the GPL and available as source code - to anybody who wants to build on it! These technologies are working, - albeit started from the command line only (and very inconvenient to - use in order to get a fully running remote X session up and running....) - </p><p> - To answer your questions: - </p><div class="itemizedlist"><ul type="disc"><li><p> - You don't need to install a terminal server; XP has RDP support built in. - </p></li><li><p> - NX is much cheaper than Citrix -- and comparable in performance, probably faster - </p></li><li><p> - You don't need to hack XP -- it just works - </p></li><li><p> - You log into the XP box from remote transparently (and I think there is no - need to change anything to get a connection, even if authentication is against a domain) - </p></li><li><p> - The NX core technologies are all Open Source and released under the GPL -- - you can today use a (very inconvenient) commandline to use it at no cost, - but you can buy a comfortable (proprietary) NX GUI frontend for money - </p></li><li><p> - NoMachine are encouraging and offering help to OSS/Free Software implementations - for such a frontend too, even if it means competition to them (they have written - to this effect even to the LTSP, KDE and GNOME developer mailing lists) - </p></li></ul></div></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2944129"></a>Network Logon Script Magic</h2></div></div><div></div></div><p> -This section needs work.

class="titlepage"><div><div><h3 class="title"><a name="id2923756"></a>Features and Benefits</h3></div></div><div></div></div><p> - The Common UNIX Print System (<a href="http://www.cups.org/" target="_top">CUPS</a>) has become very popular. All - major Linux distributions now ship it as their default printing - system. To many it is still a very mystical tool. Mostly, it - "just works" (TM). People tend to regard it as a "black box" - which they don't want to look into, as long as it works. But once - there is a little problem, they are in trouble to find out where to - start debugging it. Refer to the "Classical Printing" chapter also, it - contains a lot of information that is relevant for CUPS. - </p><p> - CUPS sports quite a few unique and powerful features. While their - basic functions may be grasped quite easily, they are also - new. Because they are different from other, more traditional printing - systems, it is best to try and not apply any prior knowledge about - printing upon this new system. Rather, try to understand CUPS - from the beginning. This documentation will lead you to a - complete understanding of CUPS. Let's start with the most basic - things first. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2923811"></a>Overview</h3></div></div><div></div></div><p> - CUPS is more than just a print spooling system. It is a complete - printer management system that complies with the new IPP - (<span class="emphasis"><em>Internet Printing Protocol</em></span>). IPP is an industry - and IETF (<span class="emphasis"><em>Internet Engineering Task Force</em></span>) - standard for network printing. Many of its functions can be managed - remotely (or locally) via a web browser (giving you a - platform-independent access to the CUPS print server). Additionally, it - has the traditional command line and several more modern GUI interfaces - (GUI interfaces developed by 3rd parties, like KDE's - overwhelming <a href="http://printing.kde.org/" target="_top">KDEPrint</a>). - </p><p> - CUPS allows creation of "raw" printers (ie: NO print file - format translation) as well as "smart" printers (i.e. CUPS does - file format conversion as required for the printer). In many ways - this gives CUPS similar capabilities to the MS Windows print - monitoring system. Of course, if you are a CUPS advocate, you would - argue that CUPS is better! In any case, let us now move on to - explore how one may configure CUPS for interfacing with MS Windows - print clients via Samba. - </p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2923880"></a>Basic Configuration of CUPS support</h2></div></div><div></div></div><p> - Printing with CUPS in the most basic <tt class="filename">smb.conf</tt> setup in Samba 3.0 (as was true for 2.2.x) only needs two - settings: <a class="indexterm" name="id2923898"></a><i class="parameter"><tt>printing</tt></i> = cups and - <a class="indexterm" name="id2923912"></a><i class="parameter"><tt>printcap</tt></i> = cups. CUPS does not need a printcap file. - However, the <tt class="filename">cupsd.conf</tt> configuration file knows of two related directives that control - how such a file will be automatically created and maintained by CUPS for the convenience of third party - applications (example: <i class="parameter"><tt>Printcap /etc/printcap</tt></i> and <i class="parameter"><tt>PrintcapFormat BSD</tt></i>). - Legacy programs often require the existence of a printcap file containing printer names or they will refuse to - print. Make sure CUPS is set to generate and maintain a printcap file! For details see - <b class="command">man cupsd.conf</b> and other CUPS-related documentation, like the wealth of documents on your CUPS server - itself: <a href="http://localhost:631/documentation.html" target="_top">http://localhost:631/documentation.html</a>. - </p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2923972"></a>Linking of smbd with libcups.so</h3></div></div><div></div></div><p> - Samba has a very special relationship to CUPS. Samba can be compiled with CUPS library support. - Most recent installations have this support enabled. Per default CUPS linking is compiled - into smbd and other Samba binaries. Of course, you can use CUPS even - if Samba is not linked against <tt class="filename">libcups.so</tt> -- but - there are some differences in required or supported configuration - then. - </p><p> - When Samba is compiled against libcups, <a class="indexterm" name="id2924002"></a><i class="parameter"><tt>printcap</tt></i> = cups - uses the CUPS API to list printers, submit jobs, query queues, etc. Otherwise it maps to the System V - commands with an additional <b class="command">-oraw</b> option for printing. On a Linux - system, you can use the <b class="command">ldd</b> utility to find out details (ldd may not be present on - other OS platforms, or its function may be embodied by a different command): - </p><pre class="screen"> -<tt class="prompt">root# </tt><b class="userinput"><tt>ldd `which smbd`</tt></b> -libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x4002d000) -libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x4005a000) -libcups.so.2 => /usr/lib/libcups.so.2 (0x40123000) -[....] -</pre><p> - The line <tt class="computeroutput">libcups.so.2 => /usr/lib/libcups.so.2 (0x40123000)</tt> shows - there is CUPS support compiled into this version of Samba. If this is the case, and printing = cups - is set, then <span class="emphasis"><em>any otherwise manually set print command in <tt class="filename">smb.conf</tt> is ignored</em></span>. - This is an important point to remember! - </p><div class="tip" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Tip</h3><p> Should it be necessary, for any reason, to set your own print commands, you can do this by setting - <a class="indexterm" name="id2924097"></a><i class="parameter"><tt>printing</tt></i> = sysv.

It will print - all Graphic, Text, PDF and PostScript file submitted from Windows - clients. However, most of your Windows users would not know how to - send these kind of files to print without opening a GUI - application. Windows clients tend to have local printer drivers - installed. And the GUI application's print buttons start a printer - driver. Your users also very rarely send files from the command - line. Unlike UNIX clients, they hardly submit graphic, text or PDF - formatted files directly to the spooler. They nearly exclusively print - from GUI applications, with a "printer driver" hooked in between the - applications native format and the print data stream. If the backend - printer is not a PostScript device, the print data stream is "binary", - sensible only for the target printer.

Also, there are frequent complaints about various jobs -being printed with their pages mixed with each other.

On the other hand, CUPS provided brilliant support for -<span class="emphasis"><em>controlling</em></span> all printer options through -standardized and well-defined "PPD files" (PostScript Printers -Description files). Plus, CUPS was designed to be easily extensible. -</p><p> -Grant already had in his database a respectable compilation -of facts about a many more printers, and the Ghostscript "drivers" -they run with.

This new development is truly amazing. -</p><p> -foomatic-rip is a very clever wrapper around the need to run -Ghostscript with a different syntax, different options, different -device selections and/or different filters for each different printer -or different spooler. At the same time it can read the PPD associated -with a print queue and modify the print job according to the user -selections. Together with this comes the 100% compliance of the new -Foomatic PPDs with the Adobe spec. Some really innovative features of -the Foomatic concept will surprise users: it will support custom paper -sizes for many printers; and it will support printing on media drawn -from different paper trays within the same job (in both cases: even -where there is no support for this from Windows-based vendor printer -drivers). -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2936409"></a>Driver Development outside</h4></div></div><div></div></div><p> -Most driver development itself does not happen within -Linuxprinting.org.

Not -only does it keep the printer and driver information, but it is -organized in a way that it can generate "PPD" files "on the fly" from -its internal XML-based datasets. While these PPDs are modelled to the -Adobe specification of "PostScript Printer Descriptions" (PPDs), the -Linuxprinting.org/Foomatic-PPDs don't normally drive PostScript -printers: they are used to describe all the bells and whistles you -could ring or blow on an Epson Stylus inkjet, or a HP Photosmart or -what-have-you. The main "trick" is one little additional line, not -envisaged by the PPD specification, starting with the "*cupsFilter" -keyword: it tells the CUPS daemon how to proceed with the PostScript -print file (old-style Foomatic-PPDs named the -<span class="emphasis"><em>cupsomatic</em></span> filter script, while the new-style -PPDs now call <span class="emphasis"><em>foomatic-rip</em></span>). This filter -script calls Ghostscript on the host system (the recommended variant -is ESP Ghostscript) to do the rendering work. foomatic-rip knows which -filter or internal device setting it should ask from Ghostscript to -convert the PostScript printjob into a raster format ready for the -target device. This usage of PPDs to describe the options of non-PS -printers was the invention of the CUPS developers. The rest is easy: -GUI tools (like KDE's marvellous <a href="http://printing.kde.org/overview/kprinter.phtml" target="_top">"kprinter"</a>, -or the GNOME <a href="http://gtklp.sourceforge.net/" target="_top">"gtklp"</a>, "xpp" and the CUPS -web interface) read the PPD too and use this information to present -the available settings to the user as an intuitive menu selection. -</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2936640"></a>foomatic-rip and Foomatic-PPD Download and Installation</h3></div></div><div></div></div><p> -Here are the steps to install a foomatic-rip driven "LaserJet 4 Plus" -compatible printer in CUPS (note that recent distributions of SuSE, -UnitedLinux and Mandrake may ship with a complete package of -Foomatic-PPDs plus the foomatic-rip utility. going directly to -Linuxprinting.org ensures you to get the latest driver/PPD files): -</p><div class="itemizedlist"><ul type="disc"><li><p>Surf to <a href="http://www.linuxprinting.org/printer_list.cgi" target="_top">http://www.linuxprinting.org/printer_list.cgi</a> -</p></li><li><p>Check the complete list of printers in the database: -<a href="http://www.linuxprinting.org/printer_list.cgi?make=Anyone" target="_top">http://www.linuxprinting.org/printer_list.cgi?make=Anyone</a> -</p></li><li><p>There select your model and click on the -link.</p></li><li><p>You'll arrive at a page listing all drivers working -with this model (for all printers, there will always be -<span class="emphasis"><em>one</em></span> recommended driver.

CUPS accepts this, -because the associated CUPS-O-Matic-/Foomatic-PPD specifies: -</p><pre class="programlisting"> - *cupsFilter: "application/vnd.cups-postscript 0 cupsomatic" -</pre><p> -This line persuades CUPS to hand the file to cupsomatic, once it has -successfully converted it to the MIME type -"application/vnd.cups-postscript". This conversion will not happen for -Jobs arriving from Windows which are auto-typed -"application/octet-stream", with the according changes in -<tt class="filename">/etc/cups/mime.types</tt> in place. -</p><p> -CUPS is widely configurable and flexible, even regarding its filtering -mechanism. Another workaround in some situations would be to have in -<tt class="filename">/etc/cups/mime.types</tt> entries as follows: -</p><pre class="programlisting"> - application/postscript application/vnd.cups-raw 0 - - application/vnd.cups-postscript application/vnd.cups-raw 0 - -</pre><p> -This would prevent all Postscript files from being filtered (rather, -they will through the virtual <span class="emphasis"><em>nullfilter</em></span> -denoted with "-"). This could only be useful for PS printers. If you -want to print PS code on non-PS printers (provided they support ASCII -text printing) an entry as follows could be useful: -</p><pre class="programlisting"> - */* application/vnd.cups-raw 0 - -</pre><p> -and would effectively send <span class="emphasis"><em>all</em></span> files to the -backend without further processing. -</p><p> -Lastly, you could have the following entry: -</p><pre class="programlisting"> -application/vnd.cups-postscript application/vnd.cups-raw 0 my_PJL_stripping_filter -</pre><p> -You will need to write a <span class="emphasis"><em>my_PJL_stripping_filter</em></span> -(could be a shellscript) that parses the PostScript and removes the -unwanted PJL. This would need to conform to CUPS filter design -(mainly, receive and pass the parameters printername, job-id, -username, jobtitle, copies, print options and possibly the -filename). It would be installed as world executable into -<tt class="filename">/usr/lib/cups/filters/</tt> and will be called by CUPS -if it encounters a MIME type "application/vnd.cups-postscript". -</p><p> -CUPS can handle <span class="emphasis"><em>-o job-hold-until=indefinite</em></span>. -This keeps the job in the queue "on hold". It will only be printed -upon manual release by the printer operator. This is a requirement in -many "central reproduction departments", where a few operators manage -the jobs of hundreds of users on some big machine, where no user is -allowed to have direct access (such as when the operators often need -to load the proper paper type before running the 10,000 page job -requested by marketing for the mailing, etc.). -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2937912"></a>Auto-Deletion or Preservation of CUPS Spool Files</h2></div></div><div></div></div><p> -Samba print files pass through two "spool" directories.

This also means you should -be able to print to the printer if it were hooked directly at your -Samba/CUPS host.

This is feature that many sites -will want to use if they migrate to Samba-3 from and NT4 style domain and do NOT want to -adopt Active Directory or an LDAP based authentication back end. This section explains -some background information regarding trust relationships and how to create them. It is now -possible for Samba-3 to trust NT4 (and vice versa), as well as to create Samba3-to-Samba3 -trusts. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2911605"></a>Features and Benefits</h2></div></div><div></div></div><p> -Samba-3 can participate in Samba-to-Samba as well as in Samba-to-MS Windows NT4 style -trust relationships. This imparts to Samba similar scalability as is possible with -MS Windows NT4. -</p><p> -Given that Samba-3 has the capability to function with a scalable backend authentication -database such as LDAP, and given it's ability to run in Primary as well as Backup Domain control -modes, the administrator would be well advised to consider alternatives to the use of -Interdomain trusts simply because by the very nature of how this works it is fragile. -That was, after all, a key reason for the development and adoption of Microsoft Active Directory. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2911633"></a>Trust Relationship Background</h2></div></div><div></div></div><p> -MS Windows NT3.x/4.0 type security domains employ a non-hierarchical security structure. -The limitations of this architecture as it affects the scalability of MS Windows networking -in large organisations is well known. Additionally, the flat namespace that results from -this design significantly impacts the delegation of administrative responsibilities in -large and diverse organisations. -</p><p> -Microsoft developed Active Directory Service (ADS), based on Kerberos and LDAP, as a means -of circumventing the limitations of the older technologies. Not every organisation is ready -or willing to embrace ADS. For small companies the older NT4 style domain security paradigm -is quite adequate, there thus remains an entrenched user base for whom there is no direct -desire to go through a disruptive change to adopt ADS. -</p><p> -Microsoft introduced with MS Windows NT the ability to allow differing security domains -to affect a mechanism so that users from one domain may be given access rights and privileges -in another domain. The language that describes this capability is couched in terms of -<span class="emphasis"><em>Trusts</em></span>. Specifically, one domain will <span class="emphasis"><em>trust</em></span> the users -from another domain. The domain from which users are available to another security domain is -said to be a trusted domain. The domain in which those users have assigned rights and privileges -is the trusting domain. With NT3.x/4.0 all trust relationships are always in one direction only, -thus if users in both domains are to have privileges and rights in each others' domain, then it is -necessary to establish two (2) relationships, one in each direction. -</p><p> -In an NT4 style MS security domain, all trusts are non-transitive. This means that if there -are three (3) domains (let's call them RED, WHITE, and BLUE) where RED and WHITE have a trust -relationship, and WHITE and BLUE have a trust relationship, then it holds that there is no -implied trust between the RED and BLUE domains. ie: Relationships are explicit and not -transitive. -</p><p> - -New to MS Windows 2000 ADS security contexts is the fact that trust relationships are two-way -by default. Also, all inter-ADS domain trusts are transitive. In the case of the RED, WHITE and BLUE -domains above, with Windows 2000 and ADS the RED and BLUE domains CAN trust each other. This is -an inherent feature of ADS domains. Samba-3 implements MS Windows NT4 -style Interdomain trusts and interoperates with MS Windows 200x ADS -security domains in similar manner to MS Windows NT4 style domains. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2911721"></a>Native MS Windows NT4 Trusts Configuration</h2></div></div><div></div></div><p> -There are two steps to creating an interdomain trust relationship.

In fact, it can support any SMB/CIFS-enabled client. One of Samba's big -strengths is that you can use it to blend your mix of Windows and Linux machines together -without requiring a separate Windows NT/2000/2003 Server. Samba is actively being developed -by a global team of about 30 active programmers and was originally developed by Andrew Tridgell. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2817919"></a>Background</h2></div></div><div></div></div><p> -Once long ago, there was a buzzword referred to as DCE/RPC. This stood for Distributed -Computing Environment/Remote Procedure Calls and conceptually was a good idea. It was -originally developed by Apollo/HP as NCA 1.0 (Network Computing Architecture) and only -ran over UDP. When there was a need to run it over TCP so that it would be compatible -with DECnet 3.0, it was redesigned, submitted to The Open Group, and officially became -known as DCE/RPC. Microsoft came along and decided, rather than pay $20 per seat to -license this technology, to reimplement DCE/RPC themselves as MSRPC. From this, the -concept continued in the form of SMB (Server Message Block, or the "what") using the -NetBIOS (Network Basic Input/Output System, or the "how") compatibility layer. You can -run SMB (i.e., transport) over several different protocols; many different implementations -arose as a result, including NBIPX (NetBIOS over IPX, NwLnkNb, or NWNBLink) and NBT -(NetBIOS over TCP/IP, or NetBT). As the years passed, NBT became the most common form -of implementation until the advance of "Direct-Hosted TCP" -- the Microsoft marketing -term for eliminating NetBIOS entirely and running SMB by itself across TCP port 445 -only. As of yet, direct-hosted TCP has yet to catch on. -</p><p> -Perhaps the best summary of the origins of SMB are voiced in the 1997 article titled, CIFS: -Common Insecurities Fail Scrutiny: -</p><p><span class="emphasis"><em> -Several megabytes of NT-security archives, random whitepapers, RFCs, the CIFS spec, the Samba -stuff, a few MS knowledge-base articles, strings extracted from binaries, and packet dumps have -been dutifully waded through during the information-gathering stages of this project, and there -are *still* many missing pieces... While often tedious, at least the way has been generously -littered with occurrences of clapping hand to forehead and muttering 'crikey, what are they -thinking? -</em></span></p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2817978"></a>Terminology</h2></div></div><div></div></div><div class="itemizedlist"><ul type="disc"><li><p> - SMB: Acronym for "Server Message Block". This is Microsoft's file and printer sharing protocol. - </p></li><li><p> - CIFS: Acronym for "Common Internet File System". Around 1996, Microsoft apparently - decided that SMB needed the word "Internet" in it, so they changed it to CIFS. - </p></li><li><p> - Direct-Hosted: A method of providing file/printer sharing services over port 445/tcp - only using DNS for name resolution instead of WINS. - </p></li><li><p> - IPC: Acronym for "Inter-Process Communication". A method to communicate specific - information between programs. - </p></li><li><p> - Marshalling: - A method of serializing (i.e., sequential ordering of) variable data - suitable for transmission via a network connection or storing in a file. The source - data can be re-created using a similar process called unmarshalling. - </p></li><li><p> - NetBIOS: Acronym for "Network Basic Input/Output System". This is not a protocol; - it is a method of communication across an existing protocol. This is a standard which - was originally developed for IBM by Sytek in 1983. To exaggerate the analogy a bit, - it can help to think of this in comparison your computer's BIOS -- it controls the - essential functions of your input/output hardware -- whereas NetBIOS controls the - essential functions of your input/output traffic via the network. Again, this is a bit - of an exaggeration but it should help that paradigm shift. What is important to realize - is that NetBIOS is a transport standard, not a protocol. Unfortunately, even technically - brilliant people tend to interchange NetBIOS with terms like NetBEUI without a second - thought; this will cause no end (and no doubt) of confusion. - </p></li><li><p> - NetBEUI: Acronym for the "NetBIOS Extended User Interface". Unlike NetBIOS, NetBEUI - is a protocol, not a standard. It is also not routable, so traffic on one side of a - router will be unable to communicate with the other side. Understanding NetBEUI is - not essential to deciphering SMB; however it helps to point out that it is not the - same as NetBIOS and to improve your score in trivia at parties. NetBEUI was originally - referred to by Microsoft as "NBF", or "The Windows NT NetBEUI Frame protocol driver". - It is not often heard from these days. - </p></li><li><p> - NBT: Acronym for "NetBIOS over TCP"; also known as "NetBT". Allows the continued use - of NetBIOS traffic proxied over TCP/IP. As a result, NetBIOS names are made - to IP addresses and NetBIOS name types are conceptually equivalent to TCP/IP ports. - This is how file and printer sharing are accomplished in Windows 95/98/ME. They - traditionally rely on three ports: NetBIOS Name Service (nbname) via UDP port 137, - NetBIOS Datagram Service (nbdatagram) via UDP port 138, and NetBIOS Session Service - (nbsession) via TCP port 139.

Users -should be educated about changes they may experience so that the change will be a welcome one -and not become an obstacle to the work they need to do. The following are factors that will -help ensure a successful migration: -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2955881"></a>Domain Layout</h4></div></div><div></div></div><p> -Samba-3 can be configured as a domain controller, a back-up domain controller (probably best called -a secondary controller), a domain member, or as a stand-alone server. The Windows network security -domain context should be sized and scoped before implementation. Particular attention needs to be -paid to the location of the primary domain controller (PDC) as well as backup controllers (BDCs). -One way in which Samba-3 differs from Microsoft technology is that if one chooses to use an LDAP -authentication backend then the same database can be used by several different domains. In a -complex organisation there can be a single LDAP database, which itself can be distributed (ie: Have -a master server and multiple slave servers) that can simultaneously serve multiple domains. -</p><p> -From a design perspective, the number of users per server, as well as the number of servers, per -domain should be scaled taking into consideration server capacity and network bandwidth. -</p><p> -A physical network segment may house several domains. Each may span multiple network segments. -Where domains span routed network segments, consider and test the performance implications of -the design and layout of a network. A Centrally located domain controller that is designed to -serve multiple routed network segments may result in severe performance problems. Check the -response time (eg: ping timing) between the remote segment and the PDC. If long (more than 100 ms) -locate a backup controller (BDC) on the remote segmanet to serve as the local authentication and -access control server. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2955930"></a>Server Share and Directory Layout</h4></div></div><div></div></div><p> -There are cardinal rules to effective network design. These can not be broken with impunity. -The most important rule: Simplicity is king in every well controlled network. Every part of -the infrastructure must be managed, the more complex it is, the greater will be the demand -of keeping systems secure and functional. -</p><p> -Keep in mind the nature of how data must be share. Physical disk space layout should be considered -carefully. Some data must be backed up. The simpler the disk layout the easier it will be to -keep track of backed needs. Identify what back media will be meet needs, consider backup to tape -, CD-ROM or (DVD-ROM), or other off-line storage medium. Plan and implement for minimum -maintenance. Leave nothing to chance in your design, above all, do not leave backups to chance: -Backup and test, validate every backup, create a disaster recovery plan and prove that it works. -</p><p> -Users should be grouped according to data access control needs. File and directory access -is best controlled via group permissions and the use of the "sticky bit" on group controlled -directories may substantially avoid file access complaints from samba share users. -</p><p> -Inexperienced network administrators often attempt elaborate techniques to set access -controls on files, directories, shares, as well as in share definitions. -Keep your design and implementation simple and document your design extensively. Have others -audit your documentation. Do not create a complex mess that your successor will not understand. -Remember, job security through complex design and implementation may cause loss of operations -and downtime to users as the new administrator learns to untangle your knots. Keep access -controls simple and effective and make sure that users will never be interrupted by stupid -complexity. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2955990"></a>Logon Scripts</h4></div></div><div></div></div><p> -Logon scripts can help to ensure that all users gain share and printer connections they need. -</p><p> -Logon scripts can be created 'on-the-fly' so that all commands executed are specific to the -rights and priviliges granted to the user.

NetBIOS based networking uses broadcast messaging to -affect browse list management. When running NetBIOS over TCP/IP, this uses UDP based messaging. -UDP messages can be broadcast or unicast. -</p><a class="indexterm" name="id2894367"></a><p> -Normally, only unicast UDP messaging can be forwarded by routers. The -<a class="indexterm" name="id2894378"></a><i class="parameter"><tt>remote announce</tt></i> parameter to smb.conf helps to project browse announcements -to remote network segments via unicast UDP. Similarly, the -<a class="indexterm" name="id2894395"></a><i class="parameter"><tt>remote browse sync</tt></i> parameter of <tt class="filename">smb.conf</tt> -implements browse list collation using unicast UDP. -</p><p> -Secondly, in those networks where Samba is the only SMB server technology, -wherever possible <tt class="filename">nmbd</tt> should be configured on one (1) machine as the WINS -server. This makes it easy to manage the browsing environment. If each network -segment is configured with it's own Samba WINS server, then the only way to -get cross segment browsing to work is by using the -<a class="indexterm" name="id2894434"></a><i class="parameter"><tt>remote announce</tt></i> and the <a class="indexterm" name="id2894448"></a><i class="parameter"><tt>remote browse sync</tt></i> -parameters to your <tt class="filename">smb.conf</tt> file. -</p><p> -<a class="indexterm" name="id2894474"></a> -If only one WINS server is used for an entire multi-segment network then -the use of the <a class="indexterm" name="id2894484"></a><i class="parameter"><tt>remote announce</tt></i> and the -<a class="indexterm" name="id2894498"></a><i class="parameter"><tt>remote browse sync</tt></i> parameters should NOT be necessary. -</p><p> -As of Samba 3 WINS replication is being worked on. The bulk of the code has -been committed, but it still needs maturation. This is NOT a supported feature -of the Samba-3.0.0 release. Hopefully, this will become a supported feature -of one of the Samba-3 release series. -</p><p> -Right now Samba WINS does not support MS-WINS replication. This means that -when setting up Samba as a WINS server there must only be one <tt class="filename">nmbd</tt> -configured as a WINS server on the network. Some sites have used multiple Samba WINS -servers for redundancy (one server per subnet) and then used -<a class="indexterm" name="id2894536"></a><i class="parameter"><tt>remote browse sync</tt></i> and <a class="indexterm" name="id2894552"></a><i class="parameter"><tt>remote announce</tt></i> -to affect browse list collation across all segments. Note that this means clients -will only resolve local names, and must be configured to use DNS to resolve names -on other subnets in order to resolve the IP addresses of the servers they can see -on other subnets. This setup is not recommended, but is mentioned as a practical -consideration (ie: an 'if all else fails' scenario). -</p><p> -Lastly, take note that browse lists are a collection of unreliable broadcast -messages that are repeated at intervals of not more than 15 minutes. This means -that it will take time to establish a browse list and it can take up to 45 -minutes to stabilise, particularly across network segments. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2894584"></a>TCP/IP - without NetBIOS</h3></div></div><div></div></div><p> -<a class="indexterm" name="id2894596"></a> -<a class="indexterm" name="id2894604"></a> -<a class="indexterm" name="id2894613"></a> -All TCP/IP using systems use various forms of host name resolution.

The exact method by which this name registration -takes place is determined by whether or not the MS Windows client/server -has been given a WINS server address, whether or not LMHOSTS lookup -is enabled, or if DNS for NetBIOS name resolution is enabled, etc. -</p><p> -In the case where there is no WINS server, all name registrations as -well as name lookups are done by UDP broadcast. This isolates name -resolution to the local subnet, unless LMHOSTS is used to list all -names and IP addresses. In such situations Samba provides a means by -which the Samba server name may be forcibly injected into the browse -list of a remote MS Windows network (using the -<a class="indexterm" name="id2894933"></a><i class="parameter"><tt>remote announce</tt></i> parameter). -</p><p> -Where a WINS server is used, the MS Windows client will use UDP -unicast to register with the WINS server. Such packets can be routed -and thus WINS allows name resolution to function across routed networks. -</p><p> -During the startup process an election will take place to create a -local master browser if one does not already exist. On each NetBIOS network -one machine will be elected to function as the domain master browser. This -domain browsing has nothing to do with MS security domain control. -Instead, the domain master browser serves the role of contacting each local -master browser (found by asking WINS or from LMHOSTS) and exchanging browse -list contents. This way every master browser will eventually obtain a complete -list of all machines that are on the network. Every 11-15 minutes an election -is held to determine which machine will be the master browser. By the nature of -the election criteria used, the machine with the highest uptime, or the -most senior protocol version, or other criteria, will win the election -as domain master browser. -</p><p> -Clients wishing to browse the network make use of this list, but also depend -on the availability of correct name resolution to the respective IP -address/addresses. -</p><p> -Any configuration that breaks name resolution and/or browsing intrinsics -will annoy users because they will have to put up with protracted -inability to use the network services. -</p><p> -Samba supports a feature that allows forced synchronisation -of browse lists across routed networks using the <a class="indexterm" name="id2894996"></a><i class="parameter"><tt>remote browse sync</tt></i> parameter in the <tt class="filename">smb.conf</tt> file. -This causes Samba to contact the local master browser on a remote network and -to request browse list synchronisation. This effectively bridges -two networks that are separated by routers. The two remote -networks may use either broadcast based name resolution or WINS -based name resolution, but it should be noted that the <a class="indexterm" name="id2895025"></a><i class="parameter"><tt>remote browse sync</tt></i> parameter provides browse list synchronisation - and -that is distinct from name to address resolution, in other -words, for cross subnet browsing to function correctly it is -essential that a name to address resolution mechanism be provided. -This mechanism could be via DNS, <tt class="filename">/etc/hosts</tt>, -and so on. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="DMB"></a>Setting up WORKGROUP Browsing</h3></div></div><div></div></div><p> -To set up cross subnet browsing on a network containing machines -in up to be in a WORKGROUP, not an NT Domain you need to set up one -Samba server to be the Domain Master Browser (note that this is *NOT* -the same as a Primary Domain Controller, although in an NT Domain the -same machine plays both roles).

Configuration of SMB -browsing has been problematic for some Samba users, hence this -document. -</p><p> -MS Windows 2000 and later, as with Samba 3 and later, can be -configured to not use NetBIOS over TCP/IP. When configured this way, -it is imperative that name resolution (using DNS/LDAP/ADS) be correctly -configured and operative. Browsing will NOT work if name resolution -from SMB machine names to IP addresses does not function correctly. -</p><p> -Where NetBIOS over TCP/IP is enabled use of a WINS server is highly -recommended to aid the resolution of NetBIOS (SMB) names to IP addresses. -WINS allows remote segment clients to obtain NetBIOS name_type information -that can NOT be provided by any other means of name resolution. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2897187"></a>Browsing support in Samba</h3></div></div><div></div></div><p> -Samba facilitates browsing.

This section -describes how to set this feature up in different settings. -</p><p> -To see browse lists that span TCP/IP subnets (ie. networks separated -by routers that don't pass broadcast traffic), you must set up at least -one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing -NetBIOS name to IP address translation to be done by doing a direct -query of the WINS server. This is done via a directed UDP packet on -port 137 to the WINS server machine. The reason for a WINS server is -that by default, all NetBIOS name to IP address translation is done -by broadcasts from the querying machine. This means that machines -on one subnet will not be able to resolve the names of machines on -another subnet without using a WINS server. -</p><p> -Remember, for browsing across subnets to work correctly, all machines, -be they Windows 95, Windows NT, or Samba servers must have the IP address -of a WINS server given to them by a DHCP server, or by manual configuration -(for Win95 and WinNT, this is in the TCP/IP Properties, under Network -settings) for Samba this is in the <tt class="filename">smb.conf</tt> file. -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2897445"></a>How does cross subnet browsing work ?</h4></div></div><div></div></div><p> -Cross subnet browsing is a complicated dance, containing multiple -moving parts. It has taken Microsoft several years to get the code -that achieves this correct, and Samba lags behind in some areas. -Samba is capable of cross subnet browsing when configured correctly. -</p><p> - Consider a network set up as <a href="NetworkBrowsing.html#browsing1" title="Figure 10.1.

Subnet 1 has 5 machines -on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume -for the moment that all these machines are configured to be in the -same workgroup (for simplicity's sake). Machine N1_C on subnet 1 -is configured as Domain Master Browser (ie. it will collate the -browse lists for the workgroup). Machine N2_D is configured as -WINS server and all the other machines are configured to register -their NetBIOS names with it. -</p><p> -As all these machines are booted up, elections for master browsers -will take place on each of the three subnets. Assume that machine -N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on -subnet 3 - these machines are known as local master browsers for -their particular subnet. N1_C has an advantage in winning as the -local master browser on subnet 1 as it is set up as Domain Master -Browser. -</p><p> -On each of the three networks, machines that are configured to -offer sharing services will broadcast that they are offering -these services. The local master browser on each subnet will -receive these broadcasts and keep a record of the fact that -the machine is offering a service. This list of records is -the basis of the browse list. For this case, assume that -all the machines are configured to offer services so all machines -will be on the browse list. -</p><p> -For each network, the local master browser on that network is -considered 'authoritative' for all the names it receives via -local broadcast. This is because a machine seen by the local -master browser via a local broadcast must be on the same -network as the local master browser and thus is a 'trusted' -and 'verifiable' resource. Machines on other networks that -the local master browsers learn about when collating their -browse lists have not been directly seen - these records are -called 'non-authoritative'. -</p><p> -At this point the browse lists look as follows (these are -the machines you would see in your network neighborhood if -you looked in it on a particular network right now). -</p><p> -</p><div class="table"><a name="id2897579"></a><p class="title"><b>Table 10.1.

An additional new - feature is the ability to make available particular software Windows applications to particular - users and/or groups. - </p><p> - Remember: NT4 policy files are named <tt class="filename">NTConfig.POL</tt> and are stored in the root - of the NETLOGON share on the domain controllers. A Windows NT4 user enters a username, a password - and selects the domain name to which the logon will attempt to take place. During the logon - process the client machine reads the NTConfig.POL file from the NETLOGON share on the authenticating - server, modifies the local registry values according to the settings in this file. - </p><p> - Windows 2K GPOs are very feature rich. They are NOT stored in the NETLOGON share, rather part of - a Windows 200x policy file is stored in the Active Directory itself and the other part is stored - in a shared (and replicated) volume called the SYSVOL folder. This folder is present on all Active - Directory domain controllers. The part that is stored in the Active Directory itself is called the - group policy container (GPC), and the part that is stored in the replicated share called SYSVOL is - known as the group policy template (GPT). - </p><p> - With NT4 clients the policy file is read and executed upon only as each user logs onto the network. - MS Windows 200x policies are much more complex - GPOs are processed and applied at client machine - startup (machine specific part) and when the user logs onto the network the user specific part - is applied. In MS Windows 200x style policy management each machine and/or user may be subject - to any number of concurrently applicable (and applied) policy sets (GPOs). Active Directory allows - the administrator to also set filters over the policy settings. No such equivalent capability - exists with NT4 style policy files. - </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2944981"></a>Administration of Win2K / XP Policies</h4></div></div><div></div></div><p> - Instead of using the tool called <span class="application">The System Policy Editor</span>, commonly called Poledit (from the - executable name <b class="command">poledit.exe</b>), <span class="acronym">GPOs</span> are created and managed using a - <span class="application">Microsoft Management Console</span> <span class="acronym">(MMC)</span> snap-in as follows:</p><div class="procedure"><ol type="1"><li><p> - Go to the Windows 200x / XP menu <span class="guimenu">Start->Programs->Administrative Tools</span> - and select the MMC snap-in called <span class="guimenuitem">Active Directory Users and Computers</span> - </p></li><li><p> - Select the domain or organizational unit (OU) that you wish to manage, then right click - to open the context menu for that object, select the properties item. - </p></li><li><p> - Now left click on the <span class="guilabel">Group Policy</span> tab, then left click on the New tab.

SWAT -does not store the configuration file in any intermediate form, rather, it stores only the -parameter settings, so when SWAT writes the smb.conf file to disk it will write only -those parameters that are at other than the default settings. The result is that all comments -will be lost from the <tt class="filename">smb.conf</tt> file.

An accurate understanding of how Samba implements each security mode as well as how to configure MS Windows clients for each mode will significantly reduce user complaints and administrator heartache. </p><p> -In the SMB/CIFS networking world, there are only two types of security: <span class="emphasis"><em>USER Level</em></span> -and <span class="emphasis"><em>SHARE Level</em></span>. We refer to these collectively as <span class="emphasis"><em>security levels</em></span>. In implementing these two <span class="emphasis"><em>security levels</em></span> Samba provides flexibilities -that are not available with Microsoft Windows NT4 / 200x servers. Samba knows of five (5) -ways that allow the security levels to be implemented. In actual fact, Samba implements -<span class="emphasis"><em>SHARE Level</em></span> security only one way, but has four ways of implementing -<span class="emphasis"><em>USER Level</em></span> security. Collectively, we call the Samba implementations -<span class="emphasis"><em>Security Modes</em></span>. These are: <span class="emphasis"><em>SHARE</em></span>, <span class="emphasis"><em>USER</em></span>, <span class="emphasis"><em>DOMAIN</em></span>, -<span class="emphasis"><em>ADS</em></span>, and <span class="emphasis"><em>SERVER</em></span> -modes. They are documented in this chapter. -</p><p> - A SMB server tells the client at startup what <span class="emphasis"><em>security level</em></span> -it is running. There are two options: <span class="emphasis"><em>share level</em></span> and -<span class="emphasis"><em>user level</em></span>. Which of these two the client receives affects -the way the client then tries to authenticate itself. It does not directly affect -(to any great extent) the way the Samba server does security. This may sound strange, -but it fits in with the client/server approach of SMB.

For migrations from an existing 2.0.x setup, or if you -continued "Win9x-style" printing in your Samba 2.2 installations, it -is more of an effort. Please read the appropriate release notes and -the HOWTO Collection for 2.2. You can follow several paths. Here are -possible scenarios for migration: -</p><div class="itemizedlist"><ul type="disc"><li><p>You need to study and apply the new Windows NT printer -and driver support. Previously used parameters <i class="parameter"><tt>printer -driver file</tt></i>, <i class="parameter"><tt>printer driver</tt></i> and -<i class="parameter"><tt>printer driver location</tt></i> are no longer -supported.</p></li><li><p>If you want to take advantage of WinNT printer driver -support you also need to migrate the Win9x/ME drivers to the new -setup.</p></li><li><p>An existing <tt class="filename">printers.def</tt> file - (the one specified in the now removed parameter <i class="parameter"><tt>printer driver file</tt></i>) will work no longer with samba 3.

The make_printerdef tool is removed -and there is no backwards compatibility for this.</p></li><li><p>You need to install a Windows 9x driver into the -<i class="parameter"><tt>[print$]</tt></i> share for a printer on your Samba -host. The driver files will be stored in the "WIN40/0" subdirectory of -<i class="parameter"><tt>[print$]</tt></i>, and some other settings and info go -into the printing-related TDBs.</p></li><li><p>If you want to migrate an existing -<tt class="filename">printers.def</tt> file into the new setup, the current -only solution is to use the Windows NT APW to install the NT drivers -and the 9x drivers. This can be scripted using smbclient and -rpcclient. See the Imprints installation client at: -</p><p> - <a href="http://imprints.sourceforge.net/" target="_top">http://imprints.sourceforge.net/</a> -</p><p> -for an example.

All - major Linux distributions now ship it as their default printing - system. To many it is still a very mystical tool. Mostly, it - "just works" (TM). People tend to regard it as a "black box" - which they don't want to look into, as long as it works. But once - there is a little problem, they are in trouble to find out where to - start debugging it.

The APW asks +the user to fill in several fields (such as printer name, driver to be used, comment, port monitor, +and so on). These parameters are passed on to Samba by the APW. If the addprinter command is designed in a +way that it can create a new printer (through writing correct printcap entries on legacy systems, or +execute the <b class="command">lpadmin</b> command on more modern systems) and create the associated share +in, then the APW will in effect really create a new printer on Samba and the UNIX print subsystem! +</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2913208"></a>Migration of Classical Printing to Samba</h2></div></div><div></div></div><p> +The basic NT-style printer driver management has not changed considerably in 3.0 over the 2.2.x releases +(apart from many small improvements). Here migration should be quite easy, especially if you followed +previous advice to stop using deprecated parameters in your setup. For migrations from an existing 2.0.x +setup, or if you continued Windows 9x/Me-style printing in your Samba 2.2 installations, it is more of +an effort. Please read the appropriate release notes and the HOWTO Collection for Samba-2.2.x. You can +follow several paths. Here are possible scenarios for migration: +</p><div class="itemizedlist"><ul type="disc"><li><p> + You need to study and apply the new Windows NT printer and driver support. Previously used + parameters <i class="parameter"><tt>printer driver file</tt></i>, <i class="parameter"><tt>printer driver</tt></i> + and <i class="parameter"><tt>printer driver location</tt></i> are no longer supported. + </p></li><li><p> + If you want to take advantage of Windows NT printer driver support, you also need to migrate the + Windows 9x/Me drivers to the new setup. + </p></li><li><p> + An existing <tt class="filename">printers.def</tt> file (the one specified in the now removed parameter + <i class="parameter"><tt>printer driver file</tt></i>) will no longer work with Samba-3. In 3.0, smbd attempts + to locate a Windows 9x/Me driver files for the printer in <i class="parameter"><tt>[print$]</tt></i> + and additional settings in the TDB and only there; if it fails, it will <span class="emphasis"><em>not</em></span> + (as 2.2.x used to do) drop down to using a <tt class="filename">printers.def</tt> (and all associated + parameters). The make_printerdef tool is removed and there is no backward compatibility for this. + </p></li><li><p>You need to install a Windows 9x/Me driver into the + <i class="parameter"><tt>[print$]</tt></i> share for a printer on your Samba + host. The driver files will be stored in the “<span class="quote">WIN40/0</span>” subdirectory of + <i class="parameter"><tt>[print$]</tt></i>, and some other settings and information go + into the printing-related TDBs.</p></li><li><p>If you want to migrate an existing + <tt class="filename">printers.def</tt> file into the new setup, the + only current + solution is to use the Windows NT APW to install the NT drivers + and the 9x/Me drivers. This can be scripted using smbclient and + rpcclient. See the Imprints installation client at: + </p><p> + <ulink url="http://imprints.sourceforge.net/">http://imprints.sourceforge.net/</ulink> + </p><p> + for an example.

And + worse, there is a huge difference (and no common root) in the way + the same document is displayed on screen and how it is presented on + paper. WYSIWYG is more difficult to achieve. This goes back to the + time, decades ago, when the predecessors of X.org, + designing the UNIX foundations and protocols for Graphical User + Interfaces, refused to take responsibility for “<span class="quote">paper output</span>” + also, as some had demanded at the time, and restricted itself to + “<span class="quote">on-screen only.</span>” (For some years now, the “<span class="quote">Xprint</span>” project has been + under development, attempting to build printing support into the X + framework, including a PostScript and a PCL driver, but it is not yet + ready for prime time.)

Because of its open specification, anybody with the + skill can start writing his own implementation of a PostScript + interpreter and use it to display PostScript files on screen or on + paper. Most graphical output devices are based on the concept of + “<span class="quote">raster images</span>” or “<span class="quote">pixels</span>” (one notable exception is pen + plotters). Of course, you can look at a PostScript file in its textual + form and you will be reading its PostScript code, the language + instructions which need to be interpreted by a rasterizer.

The other looked at the stone and said, that is a garnet - I -can turn that into a precious gem and some day it will make a princess very happy! -</p><p> -The moral of this tale: Two men, two very different perspectives regarding the same stone. -Like it or not, Samba is like that stone. Treat it the right way and it can bring great -pleasure, but if you are forced upon it and have no time for its secrets then it can be -a source of discomfort. -</p><p> -Samba started out as a project that sought to provide interoperability for MS Windows 3.x -clients with a UNIX server. It has grown up a lot since its humble beginnings and now provides -features and functionality fit for large scale deployment. It also has some warts.

An accurate understanding of how Samba implements each security -mode as well as how to configure MS Windows clients for each mode will significantly -reduce user complaints and administrator heartache. -</p><p> -In the SMB/CIFS networking world, there are only two types of security: <span class="emphasis"><em>USER Level</em></span> -and <span class="emphasis"><em>SHARE Level</em></span>. We refer to these collectively as <span class="emphasis"><em>security levels</em></span>. In implementing these two <span class="emphasis"><em>security levels</em></span> Samba provides flexibilities -that are not available with Microsoft Windows NT4 / 200x servers. Samba knows of five (5) -ways that allow the security levels to be implemented. In actual fact, Samba implements -<span class="emphasis"><em>SHARE Level</em></span> security only one way, but has four ways of implementing -<span class="emphasis"><em>USER Level</em></span> security. Collectively, we call the Samba implementations -<span class="emphasis"><em>Security Modes</em></span>. These are: <span class="emphasis"><em>SHARE</em></span>, <span class="emphasis"><em>USER</em></span>, <span class="emphasis"><em>DOMAIN</em></span>, -<span class="emphasis"><em>ADS</em></span>, and <span class="emphasis"><em>SERVER</em></span> -modes. They are documented in this chapter. -</p><p> - A SMB server tells the client at startup what <span class="emphasis"><em>security level</em></span> -it is running. There are two options: <span class="emphasis"><em>share level</em></span> and -<span class="emphasis"><em>user level</em></span>. Which of these two the client receives affects -the way the client then tries to authenticate itself. It does not directly affect -(to any great extent) the way the Samba server does security. This may sound strange, -but it fits in with the client/server approach of SMB. In SMB everything is initiated -and controlled by the client, and the server can only tell the client what is -available and whether an action is allowed. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2885276"></a>User Level Security</h3></div></div><div></div></div><p> -We will describe <span class="emphasis"><em>user level</em></span> security first, as it's simpler. -In <span class="emphasis"><em>user level</em></span> security, the client will send a -<span class="emphasis"><em>session setup</em></span> command directly after the protocol negotiation. -This contains a username and password. The server can either accept or reject that -username/password combination. Note that at this stage the server has no idea what -share the client will eventually try to connect to, so it can't base the -<span class="emphasis"><em>accept/reject</em></span> on anything other than: -</p><div class="orderedlist"><ol type="1"><li><p>The username/password</p></li><li><p>The name of the client machine</p></li></ol></div><p> -If the server accepts the username/password then the client expects to be able to -mount shares (using a <span class="emphasis"><em>tree connection</em></span>) without specifying a -password. It expects that all access rights will be as the username/password -specified in the <span class="emphasis"><em>session setup</em></span>. -</p><p> -It is also possible for a client to send multiple <span class="emphasis"><em>session setup</em></span> -requests. When the server responds, it gives the client a <span class="emphasis"><em>uid</em></span> to use -as an authentication tag for that username/password. The client can maintain multiple -authentication contexts in this way (WinDD is an example of an application that does this). -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2885368"></a>Example Configuration</h4></div></div><div></div></div><p> -The <tt class="filename">smb.conf</tt> parameter that sets <span class="emphasis"><em>User Level Security</em></span> is: -</p><table class="simplelist" border="0" summary="Simple list"><tr><td><i class="parameter"><tt>security = user</tt></i></td></tr></table><p> -This is the default setting since samba-2.2.x. -</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2885414"></a>Share Level Security</h3></div></div><div></div></div><p> -Ok, now for share level security. In share level security, the client authenticates -itself separately for each share. It will send a password along with each -<span class="emphasis"><em>tree connection</em></span> (share mount). It does not explicitly send a -username with this operation. The client expects a password to be associated -with each share, independent of the user. This means that Samba has to work out what -username the client probably wants to use. It is never explicitly sent the username. -Some commercial SMB servers such as NT actually associate passwords directly with -shares in share level security, but Samba always uses the unix authentication scheme -where it is a username/password pair that is authenticated, not a share/password pair. -</p><p> -To gain understanding of the MS Windows networking parallels to this, one should think -in terms of MS Windows 9x/Me where one can create a shared folder that provides read-only -or full access, with or without a password. -</p><p> -Many clients send a <span class="emphasis"><em>session setup</em></span> even if the server is in share -level security. They normally send a valid username but no password. Samba records -this username in a list of <span class="emphasis"><em>possible usernames</em></span>.

There are two main ways -of accessing the CVS server on this host. -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2961335"></a>Access via CVSweb</h4></div></div><div></div></div><a class="indexterm" name="id2961344"></a><p> -You can access the source code via your -favourite WWW browser. This allows you to access the contents of -individual files in the repository and also to look at the revision -history and commit logs of individual files. You can also ask for a diff -listing between any two versions on the repository. -</p><p> -Use the URL : <a href="http://samba.org/cgi-bin/cvsweb" target="_top">http://samba.org/cgi-bin/cvsweb</a> -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2961383"></a>Access via cvs</h4></div></div><div></div></div><p> -You can also access the source code via a -normal cvs client. This gives you much more control over what you can -do with the repository and allows you to checkout whole source trees -and keep them up to date via normal cvs commands. This is the -preferred method of access if you are a developer and not -just a casual browser. -</p><p> -To download the latest cvs source code, point your -browser at the URL : -<a href="http://www.cyclic.com/" target="_top">http://www.cyclic.com/</a>. -and click on the 'How to get cvs' link. CVS is free software under -the GNU GPL (as is Samba). Note that there are several graphical CVS clients -which provide a graphical interface to the sometimes mundane CVS commands. -Links to theses clients are also available from the Cyclic website. -</p><p> -To gain access via anonymous cvs use the following steps. -For this example it is assumed that you want a copy of the -samba source code. For the other source code repositories -on this system just substitute the correct package name -</p><div class="procedure"><p class="title"><b>Procedure 36.1.

An example of this is what happens when an MS Windows client -wants to locate a domain logon server. It finds this service and the IP -address of a server that provides it by performing a lookup (via a -NetBIOS broadcast) for enumeration of all machines that have -registered the name type *<1c>. A logon request is then sent to each -IP address that is returned in the enumerated list of IP addresses. -Whichever machine first replies then ends up providing the logon services. -</p><p> -The name "workgroup" or "domain" really can be confusing since these -have the added significance of indicating what is the security -architecture of the MS Windows network. The term "workgroup" indicates -that the primary nature of the network environment is that of a -peer-to-peer design. In a WORKGROUP all machines are responsible for -their own security, and generally such security is limited to use of -just a password (known as SHARE MODE security). In most situations -with peer-to-peer networking the users who control their own machines -will simply opt to have no security at all. It is possible to have -USER MODE security in a WORKGROUP environment, thus requiring use -of a user name and a matching password. -</p><p> -MS Windows networking is thus predetermined to use machine names -for all local and remote machine message passing. The protocol used is -called Server Message Block (SMB) and this is implemented using -the NetBIOS protocol (Network Basic Input Output System). NetBIOS can -be encapsulated using LLC (Logical Link Control) protocol - in which case -the resulting protocol is called NetBEUI (Network Basic Extended User -Interface). NetBIOS can also be run over IPX (Internetworking Packet -Exchange) protocol as used by Novell NetWare, and it can be run -over TCP/IP protocols - in which case the resulting protocol is called -NBT or NetBT, the NetBIOS over TCP/IP. -</p><p> -MS Windows machines use a complex array of name resolution mechanisms. -Since we are primarily concerned with TCP/IP this demonstration is -limited to this area. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2952629"></a>The NetBIOS Name Cache</h3></div></div><div></div></div><p> -All MS Windows machines employ an in memory buffer in which is -stored the NetBIOS names and IP addresses for all external -machines that that machine has communicated with over the -past 10-15 minutes.

Each entry should be kept on an individual line. -# The IP address should be placed in the first column followed by the -# corresponding computername. The address and the computername -# should be separated by at least one space or tab. The "#" character -# is generally used to denote the start of a comment (see the exceptions -# below). -# -# This file is compatible with Microsoft LAN Manager 2.x TCP/IP lmhosts -# files and offers the following extensions: -# -# #PRE -# #DOM:<domain> -# #INCLUDE <filename> -# #BEGIN_ALTERNATE -# #END_ALTERNATE -# \0xnn (non-printing character support) -# -# Following any entry in the file with the characters "#PRE" will cause -# the entry to be preloaded into the name cache. By default, entries are -# not preloaded, but are parsed only after dynamic name resolution fails. -# -# Following an entry with the "#DOM:<domain>" tag will associate the -# entry with the domain specified by <domain>. This affects how the -# browser and logon services behave in TCP/IP environments. To preload -# the host name associated with #DOM entry, it is necessary to also add a -# #PRE to the line. The <domain> is always preloaded although it will not -# be shown when the name cache is viewed. -# -# Specifying "#INCLUDE <filename>" will force the RFC NetBIOS (NBT) -# software to seek the specified <filename> and parse it as if it were -# local. <filename> is generally a UNC-based name, allowing a -# centralized lmhosts file to be maintained on a server. -# It is ALWAYS necessary to provide a mapping for the IP address of the -# server prior to the #INCLUDE. This mapping must use the #PRE directive. -# In addition the share "public" in the example below must be in the -# LanManServer list of "NullSessionShares" in order for client machines to -# be able to read the lmhosts file successfully. This key is under -# \machine\system\currentcontrolset\services\lanmanserver\ -# parameters\nullsessionshares -# in the registry. Simply add "public" to the list found there. -# -# The #BEGIN_ and #END_ALTERNATE keywords allow multiple #INCLUDE -# statements to be grouped together. Any single successful include -# will cause the group to succeed. -# -# Finally, non-printing characters can be embedded in mappings by -# first surrounding the NetBIOS name in quotations, then using the -# \0xnn notation to specify a hex value for a non-printing character. -# -# The following example illustrates all of these extensions: -# -# 102.54.94.97 rhino #PRE #DOM:networking #net group's DC -# 102.54.94.102 "appname \0x14" #special app server -# 102.54.94.123 popular #PRE #source server -# 102.54.94.117 localsrv #PRE #needed for the include -# -# #BEGIN_ALTERNATE -# #INCLUDE \\localsrv\public\lmhosts -# #INCLUDE \\rhino\public\lmhosts -# #END_ALTERNATE -# -# In the above example, the "appname" server contains a special -# character in its name, the "popular" and "localsrv" server names are -# preloaded, and the "rhino" server name is specified so it can be used -# to later #INCLUDE a centrally maintained lmhosts file if the "localsrv" -# system is unavailable. -# -# Note that the whole file is parsed including comments on each lookup, -# so keeping the number of comments to a minimum will improve performance. -# Therefore it is not advisable to simply add lmhosts file entries onto the -# end of this file. -</pre></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2952854"></a>HOSTS file</h3></div></div><div></div></div><p> -This file is usually located in MS Windows NT 4.0 or 2000 in -<tt class="filename">C:\WINNT\SYSTEM32\DRIVERS\ETC</tt> and contains -the IP Address and the IP hostname in matched pairs.

Versions of Samba before 2.2 have tried to use the native fcntl() unix -system call to implement proper record locking between different Samba clients. -This can not be fully correct due to several reasons. The simplest is the fact -that a Windows client is allowed to lock a byte range up to 2^32 or 2^64, -depending on the client OS. The unix locking only supports byte ranges up to 2^31. -So it is not possible to correctly satisfy a lock request above 2^31. There are -many more differences, too many to be listed here. -</p><p> -Samba 2.2 and above implements record locking completely independent of the -underlying unix system. If a byte range lock that the client requests happens -to fall into the range 0-2^31, Samba hands this request down to the UNIX system. -All other locks can not be seen by unix anyway. -</p><p> -Strictly an SMB server should check for locks before every read and write call on -a file. Unfortunately with the way fcntl() works this can be slow and may over-stress -the <b class="command">rpc.lockd</b>. It is also almost always unnecessary as clients are supposed to -independently make locking calls before reads and writes anyway if locking is -important to them. By default Samba only makes locking calls when explicitly asked -to by a client, but if you set <a class="indexterm" name="id2908656"></a><i class="parameter"><tt>strict locking</tt></i> = yes then it -will make lock checking calls on every read and write. -</p><p> -You can also disable byte range locking completely using <a class="indexterm" name="id2908676"></a><i class="parameter"><tt>locking</tt></i> = no. -This is useful for those shares that don't support locking or don't need it -(such as cdroms).

Because of the lightweight -nature of the Windows feature design, effective configuration of -Opportunistic Locking requires a good understanding of its limitations, -and then applying that understanding when configuring data access for -each particular customized network and client usage state. -</p><p> -Opportunistic locking essentially means that the client is allowed to download and cache -a file on their hard drive while making changes; if a second client wants to access the -file, the first client receives a break and must synchronise the file back to the server. -This can give significant performance gains in some cases; some programs insist on -synchronising the contents of the entire file back to the server for a single change. -</p><p> -Level1 Oplocks (aka just plain "oplocks") is another term for opportunistic locking. -</p><p> -Level2 Oplocks provides opportunistic locking for a file that will be treated as -<span class="emphasis"><em>read only</em></span>. Typically this is used on files that are read-only or -on files that the client has no initial intention to write to at time of opening the file. -</p><p> -Kernel Oplocks are essentially a method that allows the Linux kernel to co-exist with -Samba's oplocked files, although this has provided better integration of MS Windows network -file locking with the under lying OS, SGI IRIX and Linux are the only two OS's that are -oplock aware at this time. -</p><p> -Unless your system supports kernel oplocks, you should disable oplocks if you are -accessing the same files from both UNIX/Linux and SMB clients. Regardless, oplocks should -always be disabled if you are sharing a database file (e.g., Microsoft Access) between -multiple clients, as any break the first client receives will affect synchronisation of -the entire file (not just the single record), which will result in a noticeable performance -impairment and, more likely, problems accessing the database in the first place. Notably, -Microsoft Outlook's personal folders (*.pst) react very badly to oplocks. If in doubt, -disable oplocks and tune your system from that point. -</p><p> -If client-side caching is desirable and reliable on your network, you will benefit from -turning on oplocks. If your network is slow and/or unreliable, or you are sharing your -files among other file sharing mechanisms (e.g., NFS) or across a WAN, or multiple people -will be accessing the same files frequently, you probably will not benefit from the overhead -of your client sending oplock breaks and will instead want to disable oplocks for the share. -</p><p> -Another factor to consider is the perceived performance of file access. If oplocks provide no -measurable speed benefit on your network, it might not be worth the hassle of dealing with them. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2909569"></a>Example Configuration</h3></div></div><div></div></div><p> -In the following we examine two distinct aspects of Samba locking controls. -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2909582"></a>Disabling Oplocks</h4></div></div><div></div></div><p> -You can disable oplocks on a per-share basis with the following: -</p><p> -</p><table class="simplelist" border="0" summary="Simple list"><tr><td> </td></tr><tr><td><i class="parameter"><tt>[acctdata]</tt></i></td></tr><tr><td><i class="parameter"><tt>oplocks = False</tt></i></td></tr><tr><td><i class="parameter"><tt>level2 oplocks = False</tt></i></td></tr></table><p> -</p><p> -The default oplock type is Level1.

Prior to the introduction of PAM, a decision -to use an alternative to the system password database (<tt class="filename">/etc/passwd</tt>) -would require the provision of alternatives for all programs that provide security services. -Such a choice would involve provision of alternatives to such programs as: <b class="command">login</b>, -<b class="command">passwd</b>, <b class="command">chown</b>, etc. -</p><p> -PAM provides a mechanism that disconnects these security programs from the underlying -authentication/authorization infrastructure. PAM is configured either through one file -<tt class="filename">/etc/pam.conf</tt> (Solaris), or by editing individual files that are -located in <tt class="filename">/etc/pam.d</tt>. -</p><p> -On PAM enabled UNIX/Linux systems it is an easy matter to configure the system to use any -authentication backend, so long as the appropriate dynamically loadable library modules -are available for it.

Note, when there - is a module specified for a named service, the `OTHER' entries are ignored. - </p></dd><dt><span class="term">module-type:</span></dt><dd><p> - One of (currently) four types of module. The four types are as follows: - </p><div class="itemizedlist"><ul type="disc"><li><p> - <span class="emphasis"><em>auth:</em></span> this module type provides two aspects of authenticating the user. - Firstly, it establishes that the user is who they claim to be, by instructing the application - to prompt the user for a password or other means of identification. Secondly, the module can - grant group membership (independently of the <tt class="filename">/etc/groups</tt> file discussed - above) or other privileges through its credential granting properties. - </p></li><li><p> - <span class="emphasis"><em>account:</em></span> this module performs non-authentication based account management. - It is typically used to restrict/permit access to a service based on the time of day, currently - available system resources (maximum number of users) or perhaps the location of the applicant - user `root' login only on the console. - </p></li><li><p> - <span class="emphasis"><em>session:</em></span> primarily, this module is associated with doing things that need - to be done for the user before/after they can be given service. Such things include the logging - of information concerning the opening/closing of some data exchange with a user, mounting - directories, etc. - </p></li><li><p> - <span class="emphasis"><em>password:</em></span> this last module type is required for updating the authentication - token associated with the user. Typically, there is one module for each `challenge/response' - based authentication (auth) module-type. - </p></li></ul></div></dd><dt><span class="term">control-flag:</span></dt><dd><p> - The control-flag is used to indicate how the PAM library will react to the success or failure of the - module it is associated with. Since modules can be stacked (modules of the same type execute in series, - one after another), the control-flags determine the relative importance of each module. The application - is not made aware of the individual success or failure of modules listed in the - <tt class="filename">/etc/pam.conf</tt> file. Instead, it receives a summary success or fail response from - the Linux-PAM library. The order of execution of these modules is that of the entries in the - <tt class="filename">/etc/pam.conf</tt> file; earlier entries are executed before later ones. - As of Linux-PAM v0.60, this control-flag can be defined with one of two syntaxes. - </p><p> - The simpler (and historical) syntax for the control-flag is a single keyword defined to indicate the - severity of concern associated with the success or failure of a specific module. There are four such - <span class="emphasis"><em>keywords: required, requisite, sufficient and optional</em></span>. - </p><p> - The Linux-PAM library interprets these keywords in the following manner: - </p><div class="itemizedlist"><ul type="disc"><li><p> - <span class="emphasis"><em>required:</em></span> this indicates that the success of the module is required for the - module-type facility to succeed. Failure of this module will not be apparent to the user until all - of the remaining modules (of the same module-type) have been executed. - </p></li><li><p> - <span class="emphasis"><em>requisite:</em></span> like required, however, in the case that such a module returns a - failure, control is directly returned to the application. The return value is that associated with - the first required or requisite module to fail. Note, this flag can be used to protect against the - possibility of a user getting the opportunity to enter a password over an unsafe medium. It is - conceivable that such behavior might inform an attacker of valid accounts on a system. This - possibility should be weighed against the not insignificant concerns of exposing a sensitive - password in a hostile environment. - </p></li><li><p> - <span class="emphasis"><em>sufficient:</em></span> the success of this module is deemed `sufficient' to satisfy - the Linux-PAM library that this module-type has succeeded in its purpose. In the event that no - previous required module has failed, no more `stacked' modules of this type are invoked. (Note, - in this case subsequent required modules are not invoked.). A failure of this module is not deemed - as fatal to satisfying the application that this module-type has succeeded. - </p></li><li><p> - <span class="emphasis"><em>optional:</em></span> as its name suggests, this control-flag marks the module as not - being critical to the success or failure of the user's application for service. In general, - Linux-PAM ignores such a module when determining if the module stack will succeed or fail. - However, in the absence of any definite successes or failures of previous or subsequent stacked - modules this module will determine the nature of the response to the application. One example of - this latter case, is when the other modules return something like PAM_IGNORE. - </p></li></ul></div><p> - The more elaborate (newer) syntax is much more specific and gives the administrator a great deal of control - over how the user is authenticated. This form of the control flag is delimited with square brackets and - consists of a series of value=action tokens: - </p><pre class="programlisting"> -[value1=action1 value2=action2 ...] -</pre><p> - Here, value1 is one of the following return values: success; open_err; symbol_err; service_err; - system_err; buf_err; perm_denied; auth_err; cred_insufficient; authinfo_unavail; user_unknown; maxtries; - new_authtok_reqd; acct_expired; session_err; cred_unavail; cred_expired; cred_err; no_module_data; conv_err; - authtok_err; authtok_recover_err; authtok_lock_busy; authtok_disable_aging; try_again; ignore; abort; - authtok_expired; module_unknown; bad_item; and default. The last of these (default) can be used to set - the action for those return values that are not explicitly defined. - </p><p> - The action1 can be a positive integer or one of the following tokens: ignore; ok; done; bad; die; and reset. - A positive integer, J, when specified as the action, can be used to indicate that the next J modules of the - current module-type will be skipped. In this way, the administrator can develop a moderately sophisticated - stack of modules with a number of different paths of execution. Which path is taken can be determined by the - reactions of individual modules. - </p><div class="itemizedlist"><ul type="disc"><li><p> - <span class="emphasis"><em>ignore:</em></span> when used with a stack of modules, the module's return status will not - contribute to the return code the application obtains. - </p></li><li><p> - <span class="emphasis"><em>bad:</em></span> this action indicates that the return code should be thought of as indicative - of the module failing. If this module is the first in the stack to fail, its status value will be used - for that of the whole stack. - </p></li><li><p> - <span class="emphasis"><em>die:</em></span> equivalent to bad with the side effect of terminating the module stack and - PAM immediately returning to the application. - </p></li><li><p> - <span class="emphasis"><em>ok:</em></span> this tells PAM that the administrator thinks this return code should - contribute directly to the return code of the full stack of modules. In other words, if the former - state of the stack would lead to a return of PAM_SUCCESS, the module's return code will override - this value. Note, if the former state of the stack holds some value that is indicative of a modules - failure, this 'ok' value will not be used to override that value. - </p></li><li><p> - <span class="emphasis"><em>done:</em></span> equivalent to ok with the side effect of terminating the module stack and - PAM immediately returning to the application. - </p></li><li><p> - <span class="emphasis"><em>reset:</em></span> clear all memory of the state of the module stack and start again with - the next stacked module. - </p></li></ul></div><p> - Each of the four keywords: required; requisite; sufficient; and optional, have an equivalent expression in - terms of the [...] syntax. They are as follows: - </p><p> - </p><div class="itemizedlist"><ul type="disc"><li><p> - required is equivalent to [success=ok new_authtok_reqd=ok ignore=ignore default=bad] - </p></li><li><p> - requisite is equivalent to [success=ok new_authtok_reqd=ok ignore=ignore default=die] - </p></li><li><p> - sufficient is equivalent to [success=done new_authtok_reqd=done default=ignore] - </p></li><li><p> - optional is equivalent to [success=ok new_authtok_reqd=ok default=ignore] - </p></li></ul></div><p> - </p><p> - Just to get a feel for the power of this new syntax, here is a taste of what you can do with it. With Linux-PAM-0.63, - the notion of client plug-in agents was introduced. This is something that makes it possible for PAM to support - machine-machine authentication using the transport protocol inherent to the client/server application. With the - <span class="emphasis"><em>[ ... value=action ... ]</em></span> control syntax, it is possible for an application to be configured - to support binary prompts with compliant clients, but to gracefully fall over into an alternative authentication - mode for older, legacy, applications. - </p></dd><dt><span class="term">module-path:</span></dt><dd><p> - The path-name of the dynamically loadable object file; the pluggable module itself. If the first character of the - module path is `/', it is assumed to be a complete path. If this is not the case, the given module path is appended - to the default module path: <tt class="filename">/lib/security</tt> (but see the notes above). - </p><p> - The args are a list of tokens that are passed to the module when it is invoked. Much like arguments to a typical - Linux shell command. Generally, valid arguments are optional and are specific to any given module. Invalid arguments - are ignored by a module, however, when encountering an invalid argument, the module is required to write an error - to syslog(3). For a list of generic options see the next section. - </p><p> - Note, if you wish to include spaces in an argument, you should surround that argument with square brackets. For example: - </p><pre class="programlisting"> -squid auth required pam_mysql.so user=passwd_query passwd=mada \ - db=eminence [query=select user_name from internet_service where \ - user_name='%u' and password=PASSWORD('%p') and \ - service='web_proxy'] -</pre><p> - Note, when using this convention, you can include `[' characters inside the string, and if you wish to include a `]' - character inside the string that will survive the argument parsing, you should use `\['. In other words: - </p><pre class="programlisting"> -[..[..\]..] --> ..[..].. -</pre><p> - Any line in (one of) the configuration file(s), that is not formatted correctly, will generally tend (erring on the - side of caution) to make the authentication process fail. A corresponding error is written to the system log files - with a call to syslog(3). - </p></dd></dl></div></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2950624"></a>Example System Configurations</h3></div></div><div></div></div><p> -The following is an example <tt class="filename">/etc/pam.d/login</tt> configuration file. -This example had all options been uncommented is probably not usable -as it stacks many conditions before allowing successful completion -of the login process.

Samba retrieves and stores this - information using a <a class="indexterm" name="id2898789"></a><i class="parameter"><tt>passdb backend</tt></i>.

This - similarity is, however, only skin deep. The unix scheme typically sends clear text - passwords over the network when logging in. This is bad. The SMB encryption scheme - never sends the cleartext password over the network but it does store the 16 byte - hashed values on disk. This is also bad. Why? Because the 16 byte hashed values - are a "password equivalent". You cannot derive the user's password from them, but - they could potentially be used in a modified client to gain access to a server. - This would require considerable technical knowledge on behalf of the attacker but - is perfectly possible. You should thus treat the data stored in whatever passdb - backend you use (smbpasswd file, ldap, mysql) as though it contained the cleartext - passwords of all your users. Its contents must be kept secret, and the file should - be protected accordingly. - </p><p> - Ideally we would like a password scheme that involves neither plain text passwords - on the net nor on disk. Unfortunately this is not available as Samba is stuck with - having to be compatible with other SMB systems (WinNT, WfWg, Win95 etc). - </p><p> - Windows NT 4.0 Service pack 3 changed the default setting so that plaintext passwords - are disabled from being sent over the wire. This mandates either the use of encrypted - password support or edit the Windows NT registry to re-enable plaintext passwords. - </p><p> - The following versions of MS Windows do not support full domain security protocols, - although they may log onto a domain environment: - </p><div class="itemizedlist"><ul type="disc"><li><p>MS DOS Network client 3.0 with the basic network redirector installed</p></li><li><p>Windows 95 with the network redirector update installed</p></li><li><p>Windows 98 [se]</p></li><li><p>Windows Me</p></li></ul></div><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - MS Windows XP Home does not have facilities to become a domain member and it can - not participate in domain logons. - </p></div><p> - The following versions of MS Windows fully support domain security protocols. - </p><div class="itemizedlist"><ul type="disc"><li><p>Windows NT 3.5x</p></li><li><p>Windows NT 4.0</p></li><li><p>Windows 2000 Professional</p></li><li><p>Windows 200x Server/Advanced Server</p></li><li><p>Windows XP Professional</p></li></ul></div><p> - All current release of Microsoft SMB/CIFS clients support authentication via the - SMB Challenge/Response mechanism described here.

In essence all accounts in - the local SAM require a local user account. - </p><p> - The second way to affect Windows SID to UNIX UID mapping is via the - <span class="emphasis"><em>idmap uid, idmap gid</em></span> parameters in <tt class="filename">smb.conf</tt>. - Please refer to the man page for information about these parameters. - These parameters are essential when mapping users from a remote SAM server. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="idmapbackend"></a>Mapping Common UIDs/GIDs on Distributed Machines</h3></div></div><div></div></div><p> - Samba-3 has a special facility that makes it possible to maintain identical UIDs and GIDs - on all servers in a distributed network.

There are several - disadvantages to this approach for sites with very large numbers of users (counted - in the thousands). - </p><div class="itemizedlist"><ul type="disc"><li><p> - The first is that all lookups must be performed sequentially. Given that - there are approximately two lookups per domain logon (one for a normal - session connection such as when mapping a network drive or printer), this - is a performance bottleneck for large sites. What is needed is an indexed approach - such as is used in databases. - </p></li><li><p> - The second problem is that administrators who desire to replicate a smbpasswd file - to more than one Samba server were left to use external tools such as - <b class="command">rsync(1)</b> and <b class="command">ssh(1)</b> and wrote custom, - in-house scripts. - </p></li><li><p> - And finally, the amount of information which is stored in an smbpasswd entry leaves - no room for additional attributes such as a home directory, password expiration time, - or even a Relative Identifier (RID). - </p></li></ul></div><p> - As a result of these deficiencies, a more robust means of storing user attributes - used by smbd was developed. The API which defines access to user accounts - is commonly referred to as the samdb interface (previously this was called the passdb - API, and is still so named in the Samba CVS trees). - </p><p> - Samba provides an enhanced set of passdb backends that overcome the deficiencies - of the smbpasswd plain text database.

Additionally, tdbsam is not capable of scaling for use - in sites that require PDB/BDC implementations that requires replication of the account - database.

Samba can -provide this service reliably and seamlessly for a client network -consisting of Windows workstations. -</p><p> -A Samba print service may be run on a Standalone or a Domain -member server, side by side with file serving functions, or on a -dedicated print server. It can be made as tight or as loosely secured -as needs dictate. Configurations may be simple or complex. Available -authentication schemes are essentially the same as described for file -services in previous chapters. Overall, Samba's printing support is -now able to replace an NT or Windows 2000 print server full-square, -with additional benefits in many cases. Clients may download and -install drivers and printers through their familiar "Point'n'Print" -mechanism. Printer installations executed by "Logon Scripts" are no -problem. Administrators can upload and manage drivers to be used by -clients through the familiar "Add Printer Wizard". As an additional -benefit, driver and printer management may be run from the command line -or through scripts, making it more efficient in case of large numbers -of printers. If a central accounting of print jobs (tracking every -single page and supplying the raw data for all sorts of statistical -reports) is required, this is best supported by CUPS as the print -subsystem underneath the Samba hood. -</p><p> -This chapter deals with the foundations of Samba printing, as they -implemented by the more traditional UNIX (BSD- and System V-style) -printing systems. Many things apply to CUPS, the newer Common UNIX -Printing System, too; so if you use CUPS, you might be tempted to jump -to the next chapter -- but you will certainly miss a few things if you -do so. Better to read this chapter too. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -Most of the given examples have been verified on Windows XP -Professional clients.

Samba is a "middleman". It takes -printfiles from Windows (or other SMB) clients and passes them to the -real printing system for further processing. Therefore it needs to -"talk" to two sides: to the Windows print clients and to the UNIX -printing system. Hence we must differentiate between the various -client OS types each of which behave differently, as well as the -various UNIX print subsystems, which themselves have different -features and are accessed differently. This part of the Samba HOWTO -Collection deals with the "traditional" way of UNIX printing first; -the next chapter covers in great detail the more modern -<span class="emphasis"><em>Common UNIX Printing System</em></span> -(CUPS). - -</p><div class="important" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Important</h3><p>CUPS users, be warned: don't just jump on to the next -chapter.

Just a short summary. For <i class="parameter"><tt>printing = -CUPS</tt></i>: If SAMBA is compiled against libcups, it uses the -CUPS API to submit jobs, etc. (It is a good idea also to set -<a class="indexterm" name="id2916676"></a><i class="parameter"><tt>printcap</tt></i> = cups in case your -<tt class="filename">cupsd.conf</tt> is set to write its autogenerated -printcap file to an unusual place). Otherwise Samba maps to the System -V printing commands with the -oraw option for printing, i.e. it uses -<b class="command">lp -c -d%p -oraw; rm %s</b> With <i class="parameter"><tt>printing = -cups</tt></i> , and if SAMBA is compiled against libcups, any -manually set print command will be ignored! -</p><p> -Having listed the above mappings here, you should note that there used -to be a <span class="emphasis"><em>bug</em></span> in recent 2.2.x versions which -prevented the mapping from taking effect. It lead to the -"bsd|aix|lprng|plp" settings taking effect for all other systems, for -the most important commands (the <b class="command">print</b> command, the -<b class="command">lpq</b> command and the <b class="command">lprm</b> -command). The <b class="command">lppause</b> command and the -<b class="command">lpresume</b> command remained empty. Of course, these -commands worked on bsd|aix|lprng|plp but they didn't work on -sysv|hpux|qnx systems. To work around this bug, you need to -explicitly set the commands. Use <b class="command">testparm -v</b> to -check which command takes effect. Then check that this command is -adequate and actually works for your installed print subsystem. It is -always a good idea to explicitly set up your configuration files the -way you want them to work and not rely on any built-in defaults. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2916791"></a>Setting up your own Print Commands</h3></div></div><div></div></div><p> -After a print job has finished spooling to a service, the -<a class="indexterm" name="id2916802"></a><i class="parameter"><tt>print command</tt></i> will be used by Samba via a -<span class="emphasis"><em>system()</em></span> call to process the spool file.

The print subsystem will probably not remove the spool -file on its own. So whatever command you specify on your own you -should ensure that the spool file is deleted after it has been -processed. -</p><p> -There is no difficulty with using your own customized print commands -with the traditional printing systems. However, if you don't wish to -"roll your own", you should be well informed about the default -built-in commands that Samba uses for each printing subsystem (see the -table above). In all the commands listed in the last paragraphs you -see parameters of the form <span class="emphasis"><em>%X</em></span> These are -<span class="emphasis"><em>macros</em></span>, or shortcuts, used as place holders for -the names of real objects. At the time of running a command with such -a placeholder, Samba will insert the appropriate value -automatically. Print commands can handle all Samba macro -substitutions.

Samba does not make this -distinction. By definition, the only printers of which Samba is aware -are those which are specified as shares in -. The reason is that Windows NT/200x/XP Professional -clients do not normally need to use the standard SMB printer share; -rather they can print directly to any printer on another Windows NT -host using MS-RPC. This of course assumes that the printing client has -the necessary privileges on the remote host serving the printer.

Study the -<tt class="filename">*.inf</tt> file on the CD, if it is contained. This -may not be the possible, since the *.inf file might be -missing. Unfortunately, many vendors have now started to use their own -installation programs. These installations packages are often some -sort of Windows platform archive format, plus, the files may get -re-named during the installation process. This makes it extremely -difficult to identify the driver files you need. -</p><p> -Then you only have the second option: install the driver first on a -Windows client *locally* and investigate which file names and paths it -uses after they are installed. (Note, that you need to repeat this -procedure for every client platform you want to support. We are going -to show it here for the <span class="application">W32X86</span> platform only, a -name used by Microsoft for all WinNT/2k/XP clients...) -</p><p> -A good method to recognize the driver files this is to print the test -page from the driver's <span class="guilabel">Properties</span> Dialog -(<span class="guilabel">General</span> tab). Then look at the list of driver -files named on the printout. You'll need to recognize what Windows -(and Samba) are calling the <span class="guilabel">Driver File</span> , the -<span class="guilabel">Data File</span>, the <span class="guilabel">Config File</span>, -the <span class="guilabel">Help File</span> and (optionally) the -<span class="guilabel">Dependent Driver Files</span> (this may vary slightly -for Windows NT). You need to remember all names (or better take a -note) for the next steps. -</p><p> -Another method to quickly test the driver filenames and related paths -is provided by the <b class="command">rpcclient</b> utility. Run it with -<b class="command">enumdrivers</b> or with the -<b class="command">getdriver</b> subcommand, each in the -<span class="emphasis"><em>3</em></span> level. In the following example, -<span class="emphasis"><em>TURBO_XP</em></span> is the name of the Windows PC (in this -case it was a Windows XP Professional laptop, BTW). I had installed -the driver locally to TURBO_XP while <span class="emphasis"><em>kde-bitshop</em></span> is -the name of the Linux host from which I am working. We could run an -<span class="emphasis"><em>interactive</em></span> <b class="command">rpcclient</b> session; -then we'd get an <span class="emphasis"><em>rpcclient /></em></span> prompt and would -type the subcommands at this prompt. This is left as a good exercise -to the reader. For now we use <b class="command">rpcclient</b> with the -<tt class="option">-c</tt> parameter to execute a single subcommand -line and exit again.

In the worst cases, unreadable garbage or -nothing at all comes from the printer or they produce a harvest of -error messages when attempting to print.

Basically, the Device Mode and the -set of Printer Driver Data is a collection of settings for all print -queue properties, initialized in a sensible way. Device Modes and -Printer Driver Data should initially be set on the print server (that is -here: the Samba host) to healthy values so that the clients can start -to use them immediately. How do we set these initial healthy values? -This can be achieved by accessing the drivers remotely from an NT (or -2k/XP) client, as is discussed in the next paragraphs. -</p><p> -Be aware, that a valid Device Mode can only be initiated by a -<a class="indexterm" name="id2920558"></a><i class="parameter"><tt>printer admin</tt></i>, or root (the reason should be -obvious). Device Modes can only correctly be set by executing the -printer driver program itself. Since Samba can not execute this Win32 -platform driver code, it sets this field initially to NULL (which is -not a valid setting for clients to use).

The -toolset is still in usable form; but only for a series of older -printer models, where there are prepared packages to use.

A Samba-3 PDC can operate with an LDAP Account backend. The LDAP backend can be -either a common master LDAP server, or a slave server. The use of a slave LDAP server has the -benefit that when the master is down clients may still be able to log onto the network. -This effectively gives samba a high degree of scalability iand is a very sweet (nice) solution -for large organisations. -</p><p> -While it is possible to run a Samba-3 BDC with non-LDAP backend, the administrator will -need to figure out precisely what is the best way to replicate (copy / distribute) the -user and machine Accounts backend. -</p><p> -The use of a non-LDAP backend SAM database is particularly problematic because Domain member -servers and workstations periodically change the machine trust account password. The new -password is then stored only locally. This means that in the absence of a centrally stored -accounts database (such as that provided with an LDAP based solution) if Samba-3 is running -as a BDC, the BDC instance of the Domain member trust account password will not reach the -PDC (master) copy of the SAM. If the PDC SAM is then replicated to BDCs this results in -overwriting of the SAM that contains the updated (changed) trust account password with resulting -breakage of the domain trust. -</p><p> -Considering the number of comments and questions raised concerning how to configure a BDC -lets consider each possible option and look at the pro's and con's for each theoretical solution: -</p><div class="itemizedlist"><p class="title"><b>Backup Domain Backend Account Distribution Options</b></p><ul type="disc"><li><p> - Solution: Passwd Backend is LDAP based, BDCs use a slave LDAP server - </p><p> - Arguments For: This is a neat and manageable solution.

If the information entered -does not validate against the account information that has been stored in the Domain -Control database (the SAM, or Security Account Manager database) then a set of error -codes is returned to the workstation that has made the authentication request. -</p><p> -When the username / password pair has been validated, the Domain Controller -(authentication server) will respond with full enumeration of the account information -that has been stored regarding that user in the User and Machine Accounts database -for that Domain. This information contains a complete network access profile for -the user but excludes any information that is particular to the user's desktop profile, -or for that matter it excludes all desktop profiles for groups that the user may -belong to. It does include password time limits, password uniqueness controls, -network access time limits, account validity information, machine names from which the -user may access the network, and much more. All this information was stored in the SAM -in all versions of MS Windows NT (3.10, 3.50, 3.51, 4.0). -</p><p> -The account information (user and machine) on Domain Controllers is stored in two files, -one containing the Security information and the other the SAM. These are stored in files -by the same name in the <tt class="filename">C:\WinNT\System32\config</tt> directory. These -are the files that are involved in replication of the SAM database where Backup Domain -Controllers are present on the network. -</p><p> -There are two situations in which it is desirable to install Backup Domain Controllers: -</p><div class="itemizedlist"><ul type="disc"><li><p> - On the local network that the Primary Domain Controller is on, if there are many - workstations and/or where the PDC is generally very busy.

The design of the network, the strategic placement of - Backup Domain Controllers, together with an implementation that localises as much - of network to client interchange as possible will help to minimise wide area network - bandwidth needs (and thus costs). - </p></li></ul></div><p> -The PDC contains the master copy of the SAM. In the event that an administrator makes a -change to the user account database while physically present on the local network that -has the PDC, the change will likely be made directly to the PDC instance of the master -copy of the SAM. In the event that this update may be performed in a branch office the -change will likely be stored in a delta file on the local BDC. The BDC will then send -a trigger to the PDC to commence the process of SAM synchronisation. The PDC will then -request the delta from the BDC and apply it to the master SAM.

The parameter -<a class="indexterm" name="id2890094"></a><i class="parameter"><tt>domain master</tt></i> = no -forces the BDC not to register SAMBA<#1b> which as a unique NetBIOS -name is reserved for the Primary Domain Controller. -</p><p> -The <i class="parameter"><tt>idmap backend</tt></i> will redirect the <b class="command">winbindd</b> utility to -use the LDAP database to resolve all UIDs and GIDs for UNIX accounts. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -Samba-3 has introduced a new ID mapping facility. One of the features of this facility is that it -allows greater flexibility in how user and group IDs are handled in respect of NT Domain User and Group -SIDs. One of the new facilities provides for explicitly ensuring that UNIX / Linux UID and GID values -will be consistent on the PDC, all BDCs and all Domain Member servers. The parameter that controls this -is called <i class="parameter"><tt>idmap backend</tt></i>. Please refer to the man page for <tt class="filename">smb.conf</tt> for more information -regarding it's behaviour.

Local machine trust account password updates -are not copied back to the central server. The newer machine account password is then over -written when the SAM is copied from the PDC. The result is that the Domain member machine -on start up will find that it's passwords does not match the one now in the database and -since the startup security check will now fail, this machine will not allow logon attempts -to proceed and the account expiry error will be reported. -</p><p> -The solution: use a more robust passdb backend, such as the ldapsam backend, setting up -an slave LDAP server for each BDC, and a master LDAP server for the PDC. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2890212"></a>Can Samba be a Backup Domain Controller to an NT4 PDC?</h3></div></div><div></div></div><p> -With version 2.2, no.

The Samba Team is working on understanding and implementing the protocols, -but this work has not been finished for Samba-3. -</p><p> -Can I get the benefits of a BDC with Samba? Yes, but only to a Samba PDC. The main reason for implementing a -BDC is availability. If the PDC is a Samba machine, a second Samba machine can be set up to -service logon requests whenever the PDC is down. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2890238"></a>How do I replicate the smbpasswd file?</h3></div></div><div></div></div><p> -Replication of the smbpasswd file is sensitive. It has to be done whenever changes -to the SAM are made. Every user's password change is done in the smbpasswd file and -has to be replicated to the BDC. So replicating the smbpasswd file very often is necessary. -</p><p> -As the smbpasswd file contains plain text password equivalents, it must not be -sent unencrypted over the wire. The best way to set up smbpasswd replication from -the PDC to the BDC is to use the utility rsync. rsync can use ssh as a transport. -Ssh itself can be set up to accept <span class="emphasis"><em>only</em></span> rsync transfer without requiring the user -to type a password. -</p><p> -As said a few times before, use of this method is broken and flawed. Machine trust -accounts will go out of sync, resulting in a very broken domain. This method is -<span class="emphasis"><em>not</em></span> recommended.

Samba's pdb_ldap code supports binding to a replica -LDAP server, and will also follow referrals and rebind to the master if it ever -needs to make a modification to the database.

MS Windows networking is not particularly forgiving of -misconfiguration.

To many, this is the holy -grail of MS Windows NT and beyond networking. SSO allows users in a well designed network -to log onto any workstation that is a member of the domain that their user account is in -(or in a domain that has an appropriate trust relationship with the domain they are visiting) -and they will be able to log onto the network and access resources (shares, files, and printers) -as if they are sitting at their home (personal) workstation. This is a feature of the Domain -security protocols. -</p><p> -The benefits of Domain security are available to those sites that deploy a Samba PDC. -A Domain provides a unique network security identifier (SID). Domain user and group security -identifiers are comprised of the network SID plus a relative identifier (RID) that is unique to -the account. User and Group SIDs (the network SID plus the RID) can be used to create Access Control -Lists (ACLs) attached to network resources to provide organizational access control. UNIX systems -know only of local security identifiers. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -Network clients of an MS Windows Domain security environment must be Domain members to be -able to gain access to the advanced features provided. Domain membership involves more than just -setting the workgroup name to the Domain name. It requires the creation of a Domain trust account -for the workstation (called a machine account). Please refer to the chapter on -<a href="domain-member.html" title="Chapter 7. Domain Membership">setting up samba as a domain member</a> for more information. -</p></div><p> -The following functionalities are new to the Samba-3 release: -</p><div class="itemizedlist"><ul type="disc"><li><p> - Windows NT4 domain trusts - </p></li><li><p> - Adding users via the User Manager for Domains. This can be done on any MS Windows - client using the Nexus toolkit that is available from Microsoft's web site. - Samba-3 supports the use of the Microsoft Management Console for user management. - </p></li><li><p> - Introduces replaceable and multiple user account (authentication) - back ends. In the case where the back end is placed in an LDAP database, - Samba-3 confers the benefits of a back end that can be distributed, replicated, - and is highly scalable. - </p></li><li><p> - Implements full Unicode support. This simplifies cross locale internationalisation - support. It also opens up the use of protocols that Samba-2.2.x had but could not use due - to the need to fully support Unicode. - </p></li></ul></div><p> -The following functionalities are NOT provided by Samba-3: -</p><div class="itemizedlist"><ul type="disc"><li><p> - SAM replication with Windows NT4 Domain Controllers - (i.e. a Samba PDC and a Windows NT BDC or vice versa). This means samba - cannot operate as a BDC when the PDC is Microsoft-based or - replicate account data to Windows-BDC's. - </p></li><li><p> - Acting as a Windows 2000 Domain Controller (i.e. Kerberos and - Active Directory) - In point of fact, Samba-3 DOES have some - Active Directory Domain Control ability that is at this time - purely experimental <span class="emphasis"><em>AND</em></span> that is certain - to change as it becomes a fully supported feature some time - during the Samba-3 (or later) life cycle. However, Active Directory is - more then just SMB - it's also LDAP, Kerberos, DHCP and other protocols - (with proprietary extensions, of course). - </p></li></ul></div><p> -Windows 9x / Me / XP Home clients are not true members of a domain for reasons outlined -in this chapter. The protocol for support of Windows 9x / Me style network (domain) logons -is completely different from NT4 / Win2k type domain logons and has been officially supported -for some time. These clients use the old LanMan Network Logon facilities that are supported -in Samba since approximately the Samba-1.9.15 series. -</p><p> -Samba-3 has an implementation of group mapping between Windows NT groups -and UNIX groups (this is really quite complicated to explain in a short space). This is -discussed more fully in <a href="groupmapping.html" title="Chapter 12. Mapping MS Windows and UNIX Groups">the chapter on group mapping</a>. -</p><p> -Samba-3, like an MS Windows NT4 PDC or a Windows 200x Active Directory, needs to store -user and machine trust account information in a suitable backend data store. -Refer <a href="domain-member.html#machine-trust-accounts" title="MS Windows Workstation/Server Machine Trust Accounts">to the section on machine trust accounts</a>. With Samba-3 there can be multiple -back-ends for this. A complete discussion of account database backends can be found in -<a href="passdb.html" title="Chapter 11.

In Windows 200x Domain Control architecture this role is held by domain controllers. -There is folk lore that dictates that because of it's role in the MS Windows -network, the domain controllers should be the most powerful and most capable machine in the network. -As strange as it may seem to say this here, good over all network performance dictates that -the entire infrastructure needs to be balanced. It is advisable to invest more in Stand-Alone -(or Domain Member) servers than in the domain controllers. -</p><p> -In the case of MS Windows NT4 style domains, it is the PDC that initiates a new Domain Control database. -This forms a part of the Windows registry called the SAM (Security Account Manager). It plays a key -part in NT4 type domain user authentication and in synchronisation of the domain authentication -database with Backup Domain Controllers. -</p><p> -With MS Windows 200x Server based Active Directory domains, one domain controller initiates a potential -hierarchy of domain controllers, each with their own area of delegated control. The master domain -controller has the ability to override any down-stream controller, but a down-line controller has -control only over it's down-line. With Samba-3 this functionality can be implemented using an -LDAP based user and machine account back end. -</p><p> -New to Samba-3 is the ability to use a back-end database that holds the same type of data as -the NT4 style SAM (Security Account Manager) database (one of the registry files). -<sup>[<a name="id2887167" href="#ftn.id2887167">1</a>]</sup> -</p><p> -The <span class="emphasis"><em>Backup Domain Controller</em></span> or BDC plays a key role in servicing network -authentication requests. The BDC is biased to answer logon requests in preference to the PDC. -On a network segment that has a BDC and a PDC the BDC will be most likely to service network -logon requests. The PDC will answer network logon requests when the BDC is too busy (high load). -A BDC can be promoted to a PDC. If the PDC is on line at the time that a BDC is promoted to -PDC, the previous PDC is automatically demoted to a BDC. With Samba-3 this is NOT an automatic -operation; the PDC and BDC must be manually configured and changes need to be made likewise. -</p><p> -With MS Windows NT4, it is an install time decision what type of machine the server will be. -It is possible to change the promote a BDC to a PDC and vice versa only, but the only way -to convert a domain controller to a domain member server or a stand-alone server is to -reinstall it. The install time choices offered are: -</p><div class="itemizedlist"><ul type="disc"><li><p><span class="emphasis"><em>Primary Domain Controller</em></span> - The one that seeds the domain SAM</p></li><li><p><span class="emphasis"><em>Backup Domain Controller</em></span> - One that obtains a copy of the domain SAM</p></li><li><p><span class="emphasis"><em>Domain Member Server</em></span> - One that has NO copy of the domain SAM, rather it obtains authentication from a Domain Controller for all access controls.</p></li><li><p><span class="emphasis"><em>Stand-Alone Server</em></span> - One that plays NO part is SAM synchronisation, has it's own authentication database and plays no role in Domain security.</p></li></ul></div><p> -With MS Windows 2000 the configuration of domain control is done after the server has been -installed. Samba-3 is capable of acting fully as a native member of a Windows 200x server -Active Directory domain. -</p><p> -New to Samba-3 is the ability to function fully as an MS Windows NT4 style Domain Controller, -excluding the SAM replication components. However, please be aware that Samba-3 support the -MS Windows 200x domain control protocols also. -</p><p> -At this time any appearance that Samba-3 is capable of acting as an -<span class="emphasis"><em>Domain Controller</em></span> in native ADS mode is limited and experimental in nature. -This functionality should not be used until the Samba-Team offers formal support for it. -At such a time, the documentation will be revised to duly reflect all configuration and -management requirements. Samba can act as a NT4-style DC in a Windows 2000/XP -environment. However, there are certain compromises: - -</p><div class="itemizedlist"><ul type="disc"><li><p>No machine policy files</p></li><li><p>No Group Policy Objects</p></li><li><p>No synchronously executed AD logon scripts</p></li><li><p>Can't use ANY Active Directory management tools to manage users and machines</p></li><li><p>Registry changes tattoo the main registry, while with AD they do NOT. ie: Leave permanent changes in effect</p></li><li><p>Without AD you can not peprform the function of exporting specific applications to specific users or groups</p></li></ul></div><p> -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2887335"></a>Preparing for Domain Control</h3></div></div><div></div></div><p> -There are two ways that MS Windows machines may interact with each other, with other servers, -and with Domain Controllers: Either as <span class="emphasis"><em>Stand-Alone</em></span> systems, more commonly -called <span class="emphasis"><em>Workgroup</em></span> members, or as full participants in a security system, -more commonly called <span class="emphasis"><em>Domain</em></span> members. -</p><p> -It should be noted that <span class="emphasis"><em>Workgroup</em></span> membership involve no special configuration -other than the machine being configured so that the network configuration has a commonly used name -for it's workgroup entry.

Since the - response to the NetUserGetInfo request does not contain much more than - the user's home share, profiles for Win9X clients MUST reside in the user - home directory. - </p></li><li><p> - The client then connects to the user's home share and searches for the - user's profile.

There has been much debate over the issue of whether -or not it is ok to configure Samba as a Domain Controller in security -modes other than <tt class="constant">USER</tt>. The only security mode -which will not work due to technical reasons is <tt class="constant">SHARE</tt> -mode security. <tt class="constant">DOMAIN</tt> and <tt class="constant">SERVER</tt> -mode security are really just a variation on SMB user level security. -</p><p> -Actually, this issue is also closely tied to the debate on whether -or not Samba must be the domain master browser for its workgroup -when operating as a DC. While it may technically be possible -to configure a server as such (after all, browsing and domain logons -are two distinctly different functions), it is not a good idea to do -so. You should remember that the DC must register the DOMAIN<#1b> NetBIOS -name. This is the name used by Windows clients to locate the DC. -Windows clients do not distinguish between the DC and the DMB. -A DMB is a Domain Master Browser - see <a href="NetworkBrowsing.html#DMB" title="Setting up WORKGROUP Browsing">Domain Master Browser</a>. -For this reason, it is very wise to configure the Samba DC as the DMB. -</p><p> -Now back to the issue of configuring a Samba DC to use a mode other -than <a class="indexterm" name="id2888773"></a><i class="parameter"><tt>security</tt></i> = user. If a Samba host is configured to use -another SMB server or DC in order to validate user connection -requests, then it is a fact that some other machine on the network -(the <a class="indexterm" name="id2888790"></a><i class="parameter"><tt>password server</tt></i>) knows more about the user than the Samba host. -99% of the time, this other host is a domain controller.

The most readily available -programs for file transfer that use TCP are ftp or another TCP based -SMB server. -</p><p> -If you want to test against something like a NT or WfWg server then -you will have to disable all but TCP on either the client or -server. Otherwise you may well be using a totally different protocol -(such as NetBEUI) and comparisons may not be valid. -</p><p> -Generally you should find that Samba performs similarly to ftp at raw -transfer speed. It should perform quite a bit faster than NFS, -although this very much depends on your system. -</p><p> -Several people have done comparisons between Samba and Novell, NFS or -WinNT. In some cases Samba performed the best, in others the worst. I -suspect the biggest factor is not Samba vs some other system but the -hardware and drivers used on the various systems.

One of the great areas of maturation is in -the focus that has been given over the past decade to make it possible for anyone -anywhere to use a computer. It has not always been that way, in fact, not so long -ago it was common for software to be written for exclusive use in the country of -origin. -</p><p> -Of all the effort that has been brought to bear on providing native language support -for all computer users, the efforts of the <a href="http://www.openi18n.org/" target="_top">Openi18n organisation</a> is deserving of -special mention. -</p><p> -Samba-2.x supported a single locale through a mechanism called -<span class="emphasis"><em>codepages</em></span>.

In texts, each number will be -translated to a corresponding letter. The meaning that will be assigned -to a certain number depends on the <span class="emphasis"><em>character set(charset) -</em></span> that is used. -A charset can be seen as a table that is used to translate numbers to -letters. Not all computers use the same charset (there are charsets -with German umlauts, Japanese characters, etc). Usually a charset contains -256 characters, which means that storing a character with it takes -exactly one byte. </p><p> -There are also charsets that support even more characters, -but those need twice(or even more) as much storage space. These -charsets can contain <b class="command">256 * 256 = 65536</b> characters, which -is more then all possible characters one could think of. They are called -multibyte charsets (because they use more then one byte to -store one character). -</p><p> - A standardised multibyte charset is <a href="http://www.unicode.org/" target="_top">unicode</a>. -A big advantage of using a multibyte charset is that you only need one; there -is no need to make sure two computers use the same charset when they are -communicating. -</p><p>Old windows clients use single-byte charsets, named -'codepages' by Microsoft. However, there is no support for -negotiating the charset to be used in the smb protocol. Thus, you -have to make sure you are using the same charset when talking to an older client. -Newer clients (Windows NT, 2K, XP) talk unicode over the wire. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2953454"></a>Samba and charsets</h2></div></div><div></div></div><p> -As of samba 3.0, samba can (and will) talk unicode over the wire.

Winbind uses a UNIX implementation of Microsoft - RPC calls, Pluggable Authentication Modules, and the Name Service Switch to - allow Windows NT domain users to appear and operate as UNIX users on a UNIX - machine. This chapter describes the winbind system, explaining the functionality - it provides, how it is configured, and how it works internally. - </p><p> - Winbind provides three separate functions: - </p><div class="itemizedlist"><ul type="disc"><li><p> - Authentication of user credentials (via PAM) - </p></li><li><p> - Identity resolution (via NSS)` - </p></li><li><p> - Windindd maintains a database called winbind_idmap.tdb in which it stores - mappings between UNIX UIDs / GIDs and NT SIDs. This mapping is used only - for users and groups that do not have a local UID/GID. It stored the UID/GID - allocated from the idmap uid/gid range that it has mapped to the NT SID. - If <i class="parameter"><tt>idmap backend</tt></i> has been specified as ldapsam:url - then instead of using a local mapping winbindd will obtain this information - from the LDAP database. - </p></li></ul></div><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - If winbindd is not running, then smbd (which calls winbindd) will fall back to - using purely local information from /etc/passwd and /etc/group and no dynamic - mapping will be used. - </p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2941246"></a>Introduction</h2></div></div><div></div></div><p>It is well known that UNIX and Microsoft Windows NT have - different models for representing user and group information and - use different technologies for implementing them. This fact has - made it difficult to integrate the two systems in a satisfactory - manner.</p><p>One common solution in use today has been to create - identically named user accounts on both the UNIX and Windows systems - and use the Samba suite of programs to provide file and print services - between the two. This solution is far from perfect however, as - adding and deleting users on both sets of machines becomes a chore - and two sets of passwords are required both of which - can lead to synchronization problems between the UNIX and Windows - systems and confusion for users.</p><p>We divide the unified logon problem for UNIX machines into - three smaller problems:</p><div class="itemizedlist"><ul type="disc"><li><p>Obtaining Windows NT user and group information - </p></li><li><p>Authenticating Windows NT users - </p></li><li><p>Password changing for Windows NT users - </p></li></ul></div><p>Ideally, a prospective solution to the unified logon problem - would satisfy all the above components without duplication of - information on the UNIX machines and without creating additional - tasks for the system administrator when maintaining users and - groups on either system. The winbind system provides a simple - and elegant solution to all three components of the unified logon - problem.</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2941324"></a>What Winbind Provides</h2></div></div><div></div></div><p>Winbind unifies UNIX and Windows NT account management by - allowing a UNIX box to become a full member of a NT domain. Once - this is done the UNIX box will see NT users and groups as if - they were native UNIX users and groups, allowing the NT domain - to be used in much the same manner that NIS+ is used within - UNIX-only environments.</p><p>The end result is that whenever any - program on the UNIX machine asks the operating system to lookup - a user or group name, the query will be resolved by asking the - NT domain controller for the specified domain to do the lookup. - Because Winbind hooks into the operating system at a low level - (via the NSS name resolution modules in the C library) this - redirection to the NT domain controller is completely - transparent.</p><p>Users on the UNIX machine can then use NT user and group - names as they would use "native" UNIX names. They can chown files - so that they are owned by NT domain users or even login to the - UNIX machine and run a UNIX X-Window session as a domain user.</p><p>The only obvious indication that Winbind is being used is - that user and group names take the form DOMAIN\user and - DOMAIN\group. This is necessary as it allows Winbind to determine - that redirection to a domain controller is wanted for a particular - lookup and which trusted domain is being referenced.</p><p>Additionally, Winbind provides an authentication service - that hooks into the Pluggable Authentication Modules (PAM) system - to provide authentication via a NT domain to any PAM enabled - applications. This capability solves the problem of synchronizing - passwords between systems since all passwords are stored in a single - location (on the domain controller).</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941400"></a>Target Uses</h3></div></div><div></div></div><p>Winbind is targeted at organizations that have an - existing NT based domain infrastructure into which they wish - to put UNIX workstations or servers. Winbind will allow these - organizations to deploy UNIX workstations without having to - maintain a separate account infrastructure. This greatly - simplifies the administrative overhead of deploying UNIX - workstations into a NT based organization.</p><p>Another interesting way in which we expect Winbind to - be used is as a central part of UNIX based appliances. Appliances - that provide file and print services to Microsoft based networks - will be able to use Winbind to provide seamless integration of - the appliance into the domain.</p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2941431"></a>How Winbind Works</h2></div></div><div></div></div><p>The winbind system is designed around a client/server - architecture. A long running <b class="command">winbindd</b> daemon - listens on a UNIX domain socket waiting for requests - to arrive. These requests are generated by the NSS and PAM - clients and processed sequentially.</p><p>The technologies used to implement winbind are described - in detail below.</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941460"></a>Microsoft Remote Procedure Calls</h3></div></div><div></div></div><p>Over the last few years, efforts have been underway - by various Samba Team members to decode various aspects of - the Microsoft Remote Procedure Call (MSRPC) system. This - system is used for most network related operations between - Windows NT machines including remote management, user authentication - and print spooling. Although initially this work was done - to aid the implementation of Primary Domain Controller (PDC) - functionality in Samba, it has also yielded a body of code which - can be used for other purposes.</p><p>Winbind uses various MSRPC calls to enumerate domain users - and groups and to obtain detailed information about individual - users or groups. Other MSRPC calls can be used to authenticate - NT domain users and to change user passwords. By directly querying - a Windows PDC for user and group information, winbind maps the - NT account information onto UNIX user and group names.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941493"></a>Microsoft Active Directory Services</h3></div></div><div></div></div><p> - Since late 2001, Samba has gained the ability to - interact with Microsoft Windows 2000 using its 'Native - Mode' protocols, rather than the NT4 RPC services. - Using LDAP and Kerberos, a domain member running - winbind can enumerate users and groups in exactly the - same way as a Win2k client would, and in so doing - provide a much more efficient and - effective winbind implementation. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941516"></a>Name Service Switch</h3></div></div><div></div></div><p>The Name Service Switch, or NSS, is a feature that is - present in many UNIX operating systems. It allows system - information such as hostnames, mail aliases and user information - to be resolved from different sources. For example, a standalone - UNIX workstation may resolve system information from a series of - flat files stored on the local filesystem. A networked workstation - may first attempt to resolve system information from local files, - and then consult a NIS database for user information or a DNS server - for hostname information.</p><p>The NSS application programming interface allows winbind - to present itself as a source of system information when - resolving UNIX usernames and groups. Winbind uses this interface, - and information obtained from a Windows NT server using MSRPC - calls to provide a new source of account enumeration. Using standard - UNIX library calls, one can enumerate the users and groups on - a UNIX machine running winbind and see all users and groups in - a NT domain plus any trusted domain as though they were local - users and groups.</p><p>The primary control file for NSS is - <tt class="filename">/etc/nsswitch.conf</tt>. - When a UNIX application makes a request to do a lookup - the C library looks in <tt class="filename">/etc/nsswitch.conf</tt> - for a line which matches the service type being requested, for - example the "passwd" service type is used when user or group names - are looked up. This config line specifies which implementations - of that service should be tried and in what order. If the passwd - config line is:</p><pre class="programlisting"> -passwd: files example - </pre><p>then the C library will first load a module called - <tt class="filename">/lib/libnss_files.so</tt> followed by - the module <tt class="filename">/lib/libnss_example.so</tt>. The - C library will dynamically load each of these modules in turn - and call resolver functions within the modules to try to resolve - the request. Once the request is resolved the C library returns the - result to the application.</p><p>This NSS interface provides a very easy way for Winbind - to hook into the operating system. All that needs to be done - is to put <tt class="filename">libnss_winbind.so</tt> in <tt class="filename">/lib/</tt> - then add "winbind" into <tt class="filename">/etc/nsswitch.conf</tt> at - the appropriate place. The C library will then call Winbind to - resolve user and group names.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941652"></a>Pluggable Authentication Modules</h3></div></div><div></div></div><p>Pluggable Authentication Modules, also known as PAM, - is a system for abstracting authentication and authorization - technologies. With a PAM module it is possible to specify different - authentication methods for different system applications without - having to recompile these applications. PAM is also useful - for implementing a particular policy for authorization. For example, - a system administrator may only allow console logins from users - stored in the local password file but only allow users resolved from - a NIS database to log in over the network.</p><p>Winbind uses the authentication management and password - management PAM interface to integrate Windows NT users into a - UNIX system. This allows Windows NT users to log in to a UNIX - machine and be authenticated against a suitable Primary Domain - Controller. These users can also change their passwords and have - this change take effect directly on the Primary Domain Controller. - </p><p>PAM is configured by providing control files in the directory - <tt class="filename">/etc/pam.d/</tt> for each of the services that - require authentication. When an authentication request is made - by an application the PAM code in the C library looks up this - control file to determine what modules to load to do the - authentication check and in what order. This interface makes adding - a new authentication service for Winbind very easy, all that needs - to be done is that the <tt class="filename">pam_winbind.so</tt> module - is copied to <tt class="filename">/lib/security/</tt> and the PAM - control files for relevant services are updated to allow - authentication via winbind. See the PAM documentation - for more details.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941724"></a>User and Group ID Allocation</h3></div></div><div></div></div><p>When a user or group is created under Windows NT - is it allocated a numerical relative identifier (RID). This is - slightly different to UNIX which has a range of numbers that are - used to identify users, and the same range in which to identify - groups. It is winbind's job to convert RIDs to UNIX id numbers and - vice versa. When winbind is configured it is given part of the UNIX - user id space and a part of the UNIX group id space in which to - store Windows NT users and groups. If a Windows NT user is - resolved for the first time, it is allocated the next UNIX id from - the range. The same process applies for Windows NT groups. Over - time, winbind will have mapped all Windows NT users and groups - to UNIX user ids and group ids.</p><p>The results of this mapping are stored persistently in - an ID mapping database held in a tdb database). This ensures that - RIDs are mapped to UNIX IDs in a consistent way.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941757"></a>Result Caching</h3></div></div><div></div></div><p>An active system can generate a lot of user and group - name lookups. To reduce the network cost of these lookups winbind - uses a caching scheme based on the SAM sequence number supplied - by NT domain controllers. User or group information returned - by a PDC is cached by winbind along with a sequence number also - returned by the PDC. This sequence number is incremented by - Windows NT whenever any user or group information is modified. If - a cached entry has expired, the sequence number is requested from - the PDC and compared against the sequence number of the cached entry. - If the sequence numbers do not match, then the cached information - is discarded and up to date information is requested directly - from the PDC.</p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2941785"></a>Installation and Configuration</h2></div></div><div></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2941792"></a>Introduction</h3></div></div><div></div></div><p> -This section describes the procedures used to get winbind up and -running.
