Where is the TGT stored that is used by adclient and how can it be examined?

The adclient on *nix machine, needs a kerberos TGT (Ticket Granting Ticket) to join the domain.  The TGT is stored in /etc/krb5.ccache . The ticket can be viewed by the root account with the klist command.
# /usr/share/centrifydc/kerberos/bin/klist -fec /etc/krb5.ccache
User-added image

In this image the klist command is used to examine the expiration time for the TGT, along with the encryption type and related flags.  As with all kerberos tickets, this ticket it good for ten hours by default. At the half-life time, adclient will re-authenticate and obtain a new ticket.
