[Samba] Are "builtin" groups supposed to work with ldap?

[Luca Olivetti]

This is with 3.0.11 and the idealx smbldap-tools 0.8.7

# /opt/IDEALX/sbin/smbldap-groupshow 'Domain Admins'
dn: cn=Domain Admins,ou=Groups,dc=wetron,dc=es
objectClass: posixGroup,sambaGroupMapping

Ok, that's good

# /opt/IDEALX/sbin/smbldap-groupshow 'Administrators'
dn: cn=Administrators,ou=Groups,dc=wetron,dc=es
objectClass: posixGroup,sambaGroupMapping

# net -U luca rpc group members 'Administrators'

   cli_pipe: return critical error. Error was Call timed out: server did

Not so good. The log is saying:

  [2005/03/07 21:06:14, 0] lib/smbldap.c:smbldap_open(881)
  smbldap_open: cannot access LDAP when not root..


Let's try again as root

----------8<-------------------------------------------
# net -U Administrator rpc group members 'Administrators'
Password:

No error this time, but there's no user in the group (while 
smbldap-groupshow tells I'm in that group).
What am I doing wrong?

Bye.
