We usually have passwordless logins anyway for the job manager to work. It
isn't a security risk (at least on the WNs) because the same DN should be
mapped to the same account on all nodes, so you can only interfere with
other instances of yourself. Arguably it is an accounting issue because you
might be able to use CPU cycles which the accounting system doesn't see, but
that isn't critical at the moment.
