* pam_winbind: Avoid a use of sprintfVolker Lendecke2016-03-311-3/+3
| | | | | | | | pam_winbind depends on talloc, which depends on libreplace, so we have asprintf available. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* smbcquotas: print "NO LIMIT" only if returned quota value is 0.Uri Simchoni2016-03-311-1/+1
| | | | | | | | | | | If the user being queried has no quota, the server returns 0 as its quota. This is the observed smbd and Windows behavior, which is also documented in [MS-FSA] 2.5.1.20.

* smbd: do not cover up VFS failures to get quotaUri Simchoni2016-03-311-6/+1
| | | | | | | | | | | Now that the VFS follows the convention that get-quota returns error only on error condition, and success with zero quota if there is no quota assigned, reply with an error if failing to obtain a user's quota.

| | | | | | | | | | | Trying to differentiate between "no quota" and real error conditions - if the connection to rpc.quotad is refused it could simply mean that the remote host has no quota and therefore report this as success with no quota.

* ntquotas - skip entry if the quota is zeroUri Simchoni2016-03-311-0/+5
| | | | | | | | | | When listing user quotas, do not list the user if the driver returned success with zero quota - this signals that no quota is assigned for that user. Signed-off-by: Uri Simchoni <uri@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* nt-quotas: return 0 as indication of no quotaUri Simchoni2016-03-311-8/+0
| | | | | | | | | | | | | | | | | | | | When getting user quota, the correct value to indicate "no quota" is 0, not -1. In [MS-FSCC] section 2.4.33 it is written that -1 designates no-quota. However, careful read of that section shows that this designation is only true when setting the quota, and this section says nothing about getting the quota. In [MS-FSA] section 2.1.5.20, it is written that "If SidList includes a SID that does not map to an existing SID in the Open.File.Volume.QuotaInformation list, the object store MUST return a FILE_QUOTA_INFORMATION structure (as specified in [MS-FSCC] section 2.4.33) that is filled with zeros. This is also verified experimentally and cleared with dochelp. Signed-off-by: Uri Simchoni <uri@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

* winbind: Do per-domain xids2sids callsVolker Lendecke2016-03-301-10/+270
| | | | | | | | | | | | | | | | | | | | | | This prepares the equivalent of 2b1dd01934b657a for xids2sids. Collecting sids2xids per domain is a bit easier: SIDs carry their own domain prefix. For the reverse, we need to scan the configuration for all the idmap range definitions. It has a separate effect: It enables overlapping idmap ranges. The per-domain calls are done whenever a range matches. If the idmap child finds a successful xid2sid mapping, this will be collected as one result. This means that every range definition can contribute mappings. If there are two rfc2307 sfu domains with overlapping ranges, the domains will be queried one after the other for a specific mapping. If the defined ranges overlap, the admin has to make sure that there are no conflicts, because in the current code "the first writer wins", and the code does not specify an order (yet).
