Subject: [PATCH] Fall back to krbprincipalname when validating host auth
indicators
When adding a new host the principal cannot be determined because it
relies on either:
a) an entry to already exist
b) krbprincipalname be a component of the dn
As a result the full dn is being passed into ipapython.Kerberos
which can't parse it.
Look into the entry in validate_validate_auth_indicator() for
krbprincipalname in this case.
