> Hftp ignores all exceptions generated while trying to get a token, based on the assumption
that it means security is disabled.  Debugging problems is excruciatingly difficult when security
is enabled but something goes wrong.  Job submissions succeed, but tasks fail because the
NN rejects the user as unauthenticated.
