Can someone provide some clarification about how much GSS-API and Kerberos support is currently implemented in jcraft.jsch and if anything essential is yet to be added to make Kerberos authentication over SSH usable ?

From my initial digging it seems the RFC 4462 (http://www.ietf.org/rfc/rfc4462.txt) is the overall spec, but I'm yet to understand how much of the "must-have" requirements have already been implemented to support usage in the typical SSH environments.

Any hint, suggestion and advice is highly appreciated.
Thanks,
Alex P
