Re: [PATCH 0/1] MR7604: kerberos: Accept NULL password, libkrb5 uses cached credentials in that case.

If a username is passed to AcquireCredentialsHandle() but no password I would expect an error. Allowing this to succeed means the app might be using credentials for a different user than intended.
