Hi everybody,

I've joined a fileserver running samba 3.0.24 to an AD domain using
winbind and noticed that samba maps the "users" group SID
(5-1-5-32-545)  to gid 1001 automatically. This seems to conflict
with one of ~2000 mappings I had to "inject" in winbinds
winbindd_idmap.tdb by use of net idmap dump/restore, because the

I don't remember but I assume the restore sets the UID and
GID HWM values right ?

Yes, it does.

At the moment it looks like this (and the numbers haven't changed much since I have imported the mappings to winbindd_idmap initially):

lunkwill / # net idmap dump /var/cache/samba/winbindd_idmap.tdb | grep HWM
USER HWM 51674
GROUP HWM 10760

Thanks for the hint, but both are set to 1000-60000, which is - as far as I know - the correct setting
if domain users/groups SIDs shall resolve to uids/gids
of this range.

Definitely sounds like the HWM values are wrong.  Winbindd
uses these records to determine the next available uid/gid
which can be allocated.

Hmmm... when does winbindd allocate a gid for the "Users"-group SID? At startup time? (I couldn't find a reference to S-1-5-32-545 in the winbindd*.tdb files, so I guess that this is done on every startup...) With the HWM values you see above I don't know why winbindd allocates the gid 1001 to the "Users"-group.
Thanks for your support!

Christoph
