    Description

      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.
