Unfortunately, this can't be done currently, because XDMCP uses UDP, and
ssh can only forward TCP connections.  There might be a workaround,
though.  See this link:

I do this all the time.  As long as both machines are configured to
forward X11 (make sure you have "X11Forwarding yes" in sshd_config, and
then either put "ForwardX11 yes" in ssh_config, or use the -X
command-line option) then it all just works, transparently.
