Strange. I'm afraid I don't use a kerberos-based rsh, so I don't know
what it's looking for that it's not finding. What happens under the
covers in OMPI is that we use "rsh -F" to launch the "orted" process
on the remote node. After some network back-n-forth, the orted fork/
exec's your executable (klist, in this case). Nothing too special
there.
Do you know what klist is doing to determine that it doesn't have any
credentials? E.g., does that file /tmp/krb5cc_p3651 exist, or no? Is
there some environment variable that it passes that filename through
that we're somehow not passing down through the orted to the executable?
