gdm does not allow login

["xerid the only" <xerid hotmail com>]

I installed the latest gnome desktop (every *.tar.gz in the current source 
tree), but gdm is giving me a problem.  I created a gdm user/group (is there 
a specific home dir or shell i need to set?), then installed it as directed 
by the INSTALL file.  I then put DESKTOP="GNOME" in the 
/etc/sysconfig/desktop file, which is read by the /etc/X11/prefdm script. (I 
run RedHat).  gdm will load, but when I try to log in, it says "user does 
not exist", for every user, I dont even get to enter a password.  Are there 
any permission on files that need to be set, or setting I've missed.  THIS 
IS NOT JUST HAPPENING WITH ROOT.  gdm owns /usr/local/var/gdm. xdm works.
