Description
The GSSKrb5 mechanism has an option of using the KDC assigned session key that is contained in the service ticket the client has.

It is also possible for the mechanism to negotiate a sub-key so that each time a new session is initiated with the same service ticket, a different session key is used. Java Kerberos should follow this behaviour.
Comments
EVALUATION Added support to generate random Kerberos sub-sessions keys.
