[Samba] how can I be a domain admin in 3.0RC3 ?

[Antoine Jacoutot]

Hi !

I'm using samba-3.0RC3 as a PDC (for testing).
I'm using the ldap backend.
I created 1 user, 1 computer and some groups.

I mapped the unix groups domainadmins to "Domain admins" with 
my_personnal_sid-512.
I added my user to domainadmins.
I set "admin users = @domainadmins" in my smb.conf, but I still do not 
have domain admin rights on workstations :(

Any idea about what I did wrong ?
Thanks in advance.

Antoine
