Hello everyone, I use winbind against a Samba DC for nsswich, and on one client it works perfectly (Samba 3.5.15 on all systems). On another client, everything works except SID_TO_UID (i.e. wbinfo -i, -S ... which breaks directory listings, too). I've now tried to narrow down the problem in a level 10 log, but I need some help interpreting. In log.winbindd, I see the following when running wbinfo -S S-1-5-21-555555555-5555555555-5555555555-3032 (SID changed): ===========...

Hi, trying to investigate my xfs-acl problem I think I have found the missing part: In smbd/uid.c the function "sid_to_uid" resolves SIDs to unix user names. This is done as follows: - First the domain part of the SID is compared to the local domain (if the SID belongs to the samba server it can be resolved locally) - In any other cases winbindd is asked This works well if the samba server is the domain contro...

Hi all, I have a problem with the mapping sid -> uid. Setup: * Samba 3.0.10, security = ads, role is ads member server. * Several trusted domains * ADS is in sync with an Openldap server (posixAccount) * winbind must not use idmap (Because every Winuser already has an uid which is in ADs and on the Ldap server) Lets say we have one global domain GLOBAL and several subdomains A,B,C

...has lost write permission and some group has got full access instead. The GID of this (possible not even existing) group is exactly the result of the RID algorithm calculation. My brief investigations indicate that the function create_canon_ace_lists() from posix_acls.c calls both sid_to_gid() and sid_to_uid() in turn with the same SID just to try if it matches in one case or the other. Unfortunately, sid_to_gid() falls back to algorithmic mapping and in the case shown above it succeeds to calculate a gid out of the migrated users RID. Turning off algorithmic rid caluculation in general would solve th...

OK, this functionality got moved into idmap_cache_find_XXXX() functions which allow smbd to look directly into the winbindd idmap cache via the uid_to_sid(), gid_to_sid(), sid_to_uid(), sid_to_gid() and sids_to_unixids() functions. These functions explicitly look inside the gencache tdb used for all generic caching (with expiry time) inside Samba, so this should be pretty efficient. Does this extra layer of in-memory caching really make such a difference on top of the caching...
