I'm seeing some strange ccache behavior, would someone please explain this: Steps to reproduce 1. restart/login 2. klist, have ticket kerberos got for user at login 3. sudo -s 4. klist, no tickets 5. exit 6. klist, still have user tickets 7. sudo -s 8. klist, now there are user tickets I didn't see with first sudo Thanks ~Hua Ying
