+=============================================================================
+
+ Basic DCE/DFS Support for SAMBA 1.9.13
+
+ Jim Doyle <doyle@oec.com> 06-02-95
+
+=============================================================================
+
+Functionality:
+--------------
+
+ Per-instance authentication for DCE/DFS.
+
+Missing Functionality in this Implementation:
+---------------------------------------------
+
+ * No automatic refresh of credentials
+
+ To do so would not be that hard.. One could simply
+ stash the clear-text key in memory, spawn a key management
+ thread to wake up right before credentials expire and
+ refresh the login context.
+
+ * No UNIX Signals support (SIGCLD, SIGPIPE, SIGHUP, SIGBUS, SIGSEGV)
+
+
+ There is no support for signal processing in Samba daemons
+ that need to authenticate with DCE. The explanation for this
+ is that the smbd is linked against thread-safe libraries in
+ order to be able to use DCE authentication mechanisms.
+ Because smbd uses signal() and fork(), it represents the
+ worst case scenario for DCE portability. In order
+ to properly support signals in a forked server environment,
+ some rework of smbd is needed in order to properly
+ construct, shutdown and reconstruct asynchronous signal
+ handling threads and synchronous signal traps across the
+ parent and child. I have not had contiguous time to work
+ on it, I expect it to be a weeks worth of work to cleanly
+ integrate thread-safe signal handing into the code and
+ test it. Until I can get to this task, I will leave it up
+ to someone adventurous enough to engineer it and negotiate
+ with Andrew to integrate the changes into the mainline branch.
+
+ The lack of full signal support means that you cannot
+ rely upon SIGHUP-ing the parent daemon to refresh
+ the configuration data. Likewise, you cannot take advantage
+ of the builtin SIGBUS/SIGSEGV traps to diagnose failures.
+ You will have to halt Samba in order to make changes
+ and then have them take effect.
+
+ The SMBD server as it stands is suitable to use if you
+ already have experience with configuring and running
+ SAMBA.
+
+Tested Platforms:
+-----------------
+
+ HP-UX 9.05 / HP-UX DCE 1.2.1
+ AIX 3.2.5 / AIX DCE/6000 1.3
+ DEC OSF-1 3.0 / DEC DCE 1.3
+
+Building:
+---------
+
+ - Uncomment the the appropriate block in the Makefile
+ for the platform you wish to build on.
+
+ - Samples of Samba server configuration files for our
+ DFS environment are included in samples.dcedfs/
+
+
+
+Bugs, Suggestions, etc..

+
+ Please post them to the mailing list.
+ That way I will see them and they will become part of
+ the archives so others can share the knowledge.
