I tried earlier creating a test account making sure the UID was the same on
both nodes but it did not help. My (maybe wrong) understanding is that the
(local Open Directory) authentication information should be read with the
help of the DirectoryService daemon from the local .plist files located at
but when torque makes the connection to a remote mom this is somehow not
working (if the user who started the pbs_mom has logged out, that is). The
user accounts are just created locally on each machine. I might next try
setting up a Leopard Server and a networked file system on the master node.
This would not solve the underlying problem but might get the queue working
allowing me to resume to my actual work.

Yes there is. We have been under a brute force ssh attack for over a month
now so I just thought that we would not need further marketing of our users
and hostnames. Sorry if this seemed confusing.
