[Samba] LDAP - valid users = @group

[Adam Williams]

I think groups are broken in samba 3.2 and 3.3.  I have directories set 
770 and folders 660 and owned by specific groups and use valid users = 
@somegroup and force group = somegroup and when people in the group try 
to write to the group they get NT_STATUS_ACCESS_DENIED errors.
