that just means that the running X server is doing access control.
you have to start X without access control or hack it. I'd recommend
not having X running on cluster nodes normally (why would you!?!).
instead, I start X-requiring programs something like this:
it starts X for nothing but that command, and cleanly shuts down.
a more practical example might be:
xinit $command -- /usr/X11R6/bin/Xorg -dpms -s off -config xorg.conf

surely you can find that out from the X startup logs...
