Smart Cards in Java Kerberos

I'm not authoritative, but AFAIK there is no smart card support in Java, though there is pkcs11 support.

If I had to do it, I would do the smart card/PKINIT stuff outside Java, and then let Java use the acquired tgt.

Unfortunately, JAAS Kerberos hasn't used the smartcard. As far as I have seen, there were no PA-PK-AS-REQ/P extensions in openjdk sources. Maybe, I missed something.
