Auditing Feature in Kerberos

  I think auth_time + principal_name can be used to link the TGT and
service ticket issued by TGS. The same information can be used for
auditing. Is this fine or is there a better way to link the TGT and
service ticket issued by TGS?

Cross realm auditing is also a problem, and identifing all the hosts
involved in delegation, even within the same realm.
