> If we a little command line entry point for testing kerberos settings,
> including some automated diagnostics checks, we could simplify fielding the
> client-side support calls.
> Specifically
> * check JRE for having java crypto extensions at full key length.
> * network checks: do you know your own name?
> * Is the user kinited in?
> * if a tgt is specified, does it exist?
> * are hadoop security options consistent?
