PS5, Line 464: "bad principal format"
Does it make sense to add information on what was the input string principal 
and what's exactly wrong with the result?

PS5, Line 78:   // Test parse krb5 principal.
This is a good test for the 'happy' or 'positive' case.

I think it would be nice to add a few other cases to be explicit on our 
expectations what's returned in such cases:
  * shortened and service principals, like 'bar', '[email protected]', 
`kudu/foo.example.com`
  * malformed/unparsable principals
  * empty principal (i.e. empty string)
