[Samba] winbind_idmap.tdb not being updated

[alaslavic at havertys.com]

A few days ago I upgraded from 3.0.2 to 3.0.9, and since the 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
