Just to clarify...
Note also that ssh gives this error if you "su" to a user that has never
formally logged in (e.g., oscartst). In this case, there is no
$HOME/.Xauthority file, and you'll get this warning message.
If you login to an OSCAR cluster as the user at least once, this
.Xauthority file will be created and this warning will go away. This
obviates the need to disable X forwarding (although you may want it
disabled anyway -- it's a local policy decision; my only point here is
that LAM/OSCAR does not *require* this).
