# Kerberos Ticket Checker
#
# This script is handy if you allow kerberos tickets to expire
# on your nodes. The script will simply warn you when a node has
# kerberos tickets expiring on the current date. This will allow to
# re-initialize the tickets if you wish to do so.
#
# Nothing fancy here, all Nagios will show is the number of tickets
# that are going to (or already have) expired.
#
# An item of note:
#
# We made no provisions for the weekend. If tickets expire on the
# weekend and nobody is around, you won't see a warning on the
# Nagios console because we look for expired on the current day
# only. It's a good idea to have this warning emailed to the
# appropriate admin and if there is something critical that relies
# on Kerberos, you might want to send a page.
