I am not following the thread here. 

The existing implementation leverages off of kerberos in the client
machine and does not leverage the NASD style ticket granting with
versioning that the CMU papers advocated. Going to the NASD protocol is
OK, but that means either abandoning Kerberos or adding Kerberos ticket
honoring to the NASD versioned ticketing. This is doable, but not
