Right, I figured that out a bit later, too. I've created a file
called /etc/gdmnopassusers and added a line to my /etc/pam.d/gdm:
auth    sufficient      pam_listfile.so file=/etc/gdmnopassusers
sense=allow item=user

And presto! However, this way, I still can't tell if it's a local login
or a remote one, so a if one could use /etc/pam.d/gdm-xdmcp for remote
logins, it'd be really nice. Could that be implemented in the next
release?
