If you’re wondering why the CCacheServer daemon, that caches in memory Kerberos tickets obtained via kinit(1) is NOT starting .. that’s because of a strange bug regarding the LimitLoadToSessionType specified into the agent .plist, located into /System/Library/LaunchAgents/edu.mit.kerberos.CCacheServer.plist on OSX 10.5 systems.

You simply have to comment out these two lines:


And either

launchctl load /System/Library/LaunchAgents/edu.mit.kerberos.CCacheServer.plist

or reboot your system ;).

CCacheServer will then be instantiated when you do a kinit:

$ kinit
Please enter the password for vjt@DOMAIN.LOCAL:

$ klist
Kerberos 5 ticket cache: 'API:Initial default ccache'
Default principal: vjt@DOMAIN.LOCAL

Valid Starting     Expires            Service Principal
11/12/08 20:59:35  11/13/08 06:59:14  krbtgt/DOMAIN.LOCAL@DOMAIN.LOCAL
    renew until 11/19/08 20:59:35

The bug is strange because the LimitLoadToSessionType key actually should instruct launchd to automatically start up the daemon and run it once for every logged in user , when kinit asks its services. But, if the key is set in the .plist, a launchctl load on it fails with “nothing found to load”. Weird!
