[Samba] Restricting Access To a Workstation

[Adam Tauno Williams]

My PDC is a Samba-3.0.3pre2/LDAPSAM/Redhat box.  I'd like to restrict logon
access to a specific workstation to members of a given group.  My initial
throught was to specify a "valid users=@group" in the globals section of an
included file (smb.conf.%m kind of thing).  Only this doesn't seem to do
anything; valid users is a share only directive?  Is there anyway to limit
logon access to a specific workstation via samba?
