The xauth cookie (a sort of generated password) that authorizes user's

It does create them on the fly.  If you're getting that error message
it means it can't.

Do you have selinux enabled?  maybe it's preventing gdm from writing
to /tmp, or maybe /tmp isn't 1777 ?

The output of ls -lZd /tmp would be interesting.

Also, does /usr/bin/setenforce 0 fix things?
