When I try to log in as a user with no password set xdm asks for a

I can reproduce this problem.
I can log in with no problem using login(8) on the tty, so I tried
cp --backup /etc/pam.d/{login,xdm}
/etc/init.d/xdm
This didn't help. Nor does anything useful turn up in /var/log, even
with "debug" on all pam_unix.so entries in /etc/pam.d/common-*.

This is because the moment xdm asks for a password it already failed
to log you in. It should verify that you actually do have a password
before asking for one.
