I don't know.

I'm not an expert at X11 authentication.

What seems to work for me these days is to use "xauth" to move
authentication information between machines on which I want to run X11
clients, but which do not have an NFS mount of my current
home-directory.  Normally my home directory is shared amongst all the
machines on my local network, and X11 clients run fine this way, so I'd
guess that XDM in X11R6 uses ~/.Xauthority....

I just run "xauth list" on the machine I xdm'ed into, and then cut&paste
the appropriate line onto the tail of an "xauth add" command via an
rlogin/telnet session to the desired machine.  SSH does this
transparently for you, of course (though I wouldn't recommend running
anything but one X11 client per SSH tunnel though, at least not until
you upgrade to the V.2 protocol with proper flow control).

This "auth" cut&paste trick also has to be done for "su" sessions, since
normally HOME=/root and so xauth files are not shared with "su" sessions.

You have to do all of this anyway if you use a "real" X11 Terminal (I
have an NCD HMX colour machine next to me for netscape and other things
that require colour.... ;-).
