> The Kerberos _service check_ needs to generate it's own unique identity to use for testing and then destroy it when complete.  This will ensure that any _known_ identities (such as the smokeuser, usually ambari-qa) does not accidentally get removed if shared between clusters or if the service check is run after Kerberos is enabled. 
> The service check must perform the following steps:
> # Create a unique principal in the relevant KDC (server)
> # Test that the principal can be used to authenticate via kinit (agent)
> # Destroy the principal (server)
