Works for krb5 and SPNEGO mechanisms. Kerberos credentials are passed as credential cache names, or if there are memory based credentials, inband in the protocol. This means that the credentials buffers must be keep secret. As documented by IBM (they have the wrong prototype though) and GGF (GSS-API Extensions) back in 2001
