Sorry, I think I may have misunderstood what you were trying to do.  Looks
like you do "su sabine" on the *remote* machine -- I thought you tried
this locally.

By default, X (in XDMCP mode) limits the connections to the user logged in
via XDMCP from the target machine.  If you want other users to connect
(whether those from the X server machine, or those from the XDMCP target
machine), you'll need to add them to the access list with the xhost
command.  You may need to specify the host to add in the form that xhost
understands (i.e., the full machine name instead of "localhost").  See the
"xhost" manpage for details.

The xhost command needs to be invoked by the user who has control over the
X server (e.g., from the remote xterm).
HTH,
