[Samba] domain admin users?

[Rodrigo Camarao]

	In version 2.x the global "domain admin users" could be used to
give administrator privileges to a user/group.

	In version 3 i've some difficulties giving administrator
privileges.

	The way i found to do its by command line "net groupmap
modify ntuser='Domain Admins' unixgroup='samba'", and put the user in
samba group on unix. But it didnt work... what can i do to give
administrator privileges for a user/group?
