I could be completely wrong, but I have not managed to get gdm to
support xdmcp logins for about a year now.  Symptoms are as you
described, on Suse11 and Ubuntu8.?? systems.  Some discussion of the
problem on various forums, but no fix that I can see.  Gdm worked on
earlier versions of the same distro's.

I end up having to use kdm, which works.
