> Currently the checkTgtAndRelogin method assumes all tickets are renewable and will attempt to call refresh() on the KerberosTicket when reaching > 80% of the ticket lifetime. If the ticket is not renewable the refresh will fail and it will do a full logout/login, same as if the ticket was no longer renewable, but it could be handled more gracefully by not even calling refresh when knowing it won't work.
