[Samba] Administrator Maps winbind GID to 100 (sys)

[Eric Roseme]

Samba 3.0.22a (with backports from up to 3.0.25) on HP-UX 11iv3 (HP CIFS 
Server), "security=ADS" to W2003R2 domain, winbind running with "idmap 
backend = rid:", and "root = DOMAIN+Administrator" in username.map.

 From Administrator on a domain Vista client, using Explore to map a 
share and then set an ACL from Properties/Security/Permissions, I choose 
a Windows group from the list to add to the directory ACL.  The winbind 
GID is 12011.  The correct groupname is displayed in the Explorer 
window, but when doing a getacl from unix, the GID is 100, or sys - the 
Administrator home group.

So I went to /var/opt/samba/locks and deleted all of the cache files and 
restarted - same result.

If I set the directory to a different owner, and add the same GID with a 
different client user, then the correct winbind GID is added to the ACL.

Any idea why Administrator=root maps the sys GID to a winbind group 
name?  Log entry and smb.conf below.  Thanks,

Eric Roseme
