man smb.conf does not specifically say admin users supports @groupname syntax. Google turns up lots of examples of it being used, but everyone hanging their smb.conf's up to air does not mean they are
100% accurate either.
Here, Samba 3.0.4 in PDC mode, I can not get it to accept the name of a group in
/etc/group, user ID's only.
