Client side functionality of Kerberos is available in Mac OS X 10.2 
(Jaguar) Client and Server. Mac OS X 10.2 (Jaguar) Server supports 
some specific services with Kerberized access.  A KDC is not 
available for either release.

Mac OS X Panther Server will provide an Apple KDC in addition to the 
services available in Jaguar.

Apple needs to resolve some issues with how CUPS communicates with 
services in the user's Security Session. You'll need to get someone 
from Apple to make a statement on whether they are going to address 
these issues for Panther or not.

Looks good.
