winbind_idmap.tdb not being updated
...upgrade, the winbindd_idmap.tdb has not ever been modified, even after several restarts of samba, and reboots of the system in question. It appears that the UID mapping is still correct on the samba server, but I am just concerned that new user additions etc are not being stored to the tdb files. winbind_cache.tdb is being updated with every restart of winbind. Should the winbind_idmap.tdb file be updated regularly? Is it normal for it to go a week without being modified? I didn't pay much attention to it before, but it seems odd that it would go so long without an update. Thanks ~alex

how to clear winbind cache
...as backend. After deleting all idmap entries in ldap nothing changed. If we disable winbindd caching with -n switch we receive desired effect - users get mapped to new uids and gids. Restarting winbindd without -n reverts everything back - users are mapped to old id's. Stoping winbind, removing winbind_cache.tdb file and starting winbind doesn't solve the issue. Liutauras

Winbind local idmap/cache database security concerns

I know that the owner is root and that the each has the permissions 0600 (idmap had 0644, but I changed it to 0600). Despite that, isn't it easy enough for a user to crack the filesystem and gain access to these databases if so he/she wished? I am especially conce...

getent & winbindd on FreeBSD 5.4
...ecute 'getent passwd' it shows only the local user accounts. Executing 'getent group' also produces only the local groups. It seems the getent command that comes with the linux_base port on FreeBSD 5.4 may or may not be working. I am unable to verify it though. Doing a 'tdbdump winbind_cache.tdb' reveals that the users are being enumerated but without a corresponding *nix user id. I don't know if the tdbsam is supposed to reveal such information. TOSHARG states that for getent to work, the nsswitch.conf must be properly configured. Mine is as follows: # /etc/nsswitch.conf pass...

Samba bug 7818 / Debian bug 603729 RESOLVED finally (I think)
I thought I would post this in case it might be of help to someone else who has experienced winbind crashes since moving to 3.5.x. Back in November 2010, after upgrading to Samba 3.5.x, I started experiencing repeated winbind crashed resulting in the generation of "winbind_cache.corrupt" files. I was premature in saying the problem was resolved and the bugs could be closed because my attempted winbind fix lasted less than 36 hours. In the interim, I've been constantly monitoring and trying other things. A recent unrelated problem affecting the entire LAN ap...

Winbind confused or corrupt
...oblem is local to the one computer. Is it mis-configuration or corruption or both? (tdbdump doesn't complain about any tdb files, so perhaps any corruption would be logical rather than physical?) I have forced the following files to be re-created: /var/lib/samba/idmap_cache.tdb /var/lib/samba/winbind_cache.tdb /var/lib/samba/winbind_idmap.tdb Many files in that dir haven't been modified since 2007; the ones that have been are: /var/lib/samba/brlock.tdb /var/lib/samba/browse.dat /var/lib/samba/locking.tdb /var/lib/samba/messages.tdb /var/lib/samba/notify.tdb /var/lib/samba/registry.tdb /var/lib/...

Users created after certain date are not cached by winbind
It seems that I have some users that winbind refuses to find. As far as I can tell, all of these users were created or re-enabled (had their expiration date reset) after a certain date. I have cleared my winbind_cache.tdb and winbind_idmap.tdb to no avail. Curiously, I also noticed that even when I removed the idmap, it still came back with the original mappings. In my winbind.log, I see numerous errors of this sort when I run 'getent passwd': [2010/02/10 12:04:30, 0] winbindd/idmap.c:201() idmap_al...
