You'd want to talk to Max (Weijun) as he has primary responsibility for
the Kerberos code, but so far it sounds very reasonable to me.
Looks like you are setup in the SCA database, it would be best to
discuss it here with Max and others that would be interested, and if you
develop a patch, please file it in the new bugzilla instance.
Thanks, good luck!
