Just to reiterate.
1) You have a server that got rebooted.
2) After reboot "kinit admin" works
3) klist shows tickets
4) logs show no errors
5) You can do ldap search - no problem
6) You stop FF and start it and it says "Kerberos ticket is no longer valid"

This is very similar to thread started by David Sastre with title
"Problem with webui: kerberos ticket no longer valid".
The start of the thread is in August and the end is in September archive.
It might have an answer for you.
