[Samba] administrator account unknown on a DC member

[Nicolas Boissé]

Hello

On a DC member, I can see all AD users with "getent passwd" command, 
except the Administrator account.

The administrator account has a UIDnumber (3002).

my smb.conf :

...
idmap config * : backend = tdb
idmap config * : range = 3000-7999
idmap config DOM:backend = ad
idmap config DOM:schema_mode = rfc2307
idmap config DOM:range = 10000-999999
idmap config DOM:unix_nss_info = yes
...

Any idea of what's wrong with it ?
