question on x windows

[Aaron Bliss]

I have this working.  Turned out to be bad gdm custom.conf file.  
Everything seems to be working fine now.  Is there a way to require a 
user be in a certain group in order to connect to gdm or xwindows?  In 
sshd_conf, there is a AllowGroups option.  Is there any simular way to 
restirct access for gdm?  Thanks.
