Dan, thanks for all that info but my understanding is that what you
have done here is set up the machine to allow it to be logged into from
a remote machine. In other words, be an XMNCP server. What I'm looking
for is how to set up gdm to allow me to choose another machine to log
in to from this machine, or put another way, be an XDMCP client.

The machine I have set up as an XDMCP server is a SuSE machine running
kdm. On that machine, there is a menu button that allows to to select
"Remote login" as an option which brings up a list of machines that are
set up as XDMCP servers. What I'm looking for is the gdm equivalent of
the menu->remote login option.

I've added
AllowAdd=true
Broadcast=true 
to the [chooser] section of /etc/gdm/custom.conf but that didn't change
anything

Thanks,
Steve
