When I try to print to my CUPS print server it makes me enter my username and password to authenticate, then it prints my job. How do I configure it properly so that it uses my ticket I received upon login to authenticate without prompting me again? Thanks, if you need anymore information please let me know.

Probably the delegation wasn't working due to out-of-date service information. Although in my experience Kerberos is all magic and needs to be knocked around from time-to-time to keep it working… :(

The CUPS error_log file probably would have logged something when it tried to create its context…

(FWIW, CUPS 1.5 has greatly simplified Kerberos configuration requirements and should work more reliably/easily and with more configurations…)
