ktkt_warnd - Kerberos warning daemon
ktkt_warnd is a daemon on Kerberos clients that can warn users when their Kerberos tickets are about to expire or renew the tickets before they expire. It is invoked by inetd when a ticket-granting ticket (TGT) is obtained for the first time, such as after using the kinit command. ktkt_warnd can be configured through per user and system configuration files on the client. In the configuration files, you can specify that the user be supplied notice of ticket expiration—through terminal, mail, or syslog—or to renew the TGT. See the warn.conf(5) manual page for further details.

Per-user Kerberos warning configuration file
If the user's configuration file does not exist, /etc/krb5/warn.conf will be used.
See attributes(7) for descriptions of the following attributes:
The auto-renew of the TGT is attempted only if the user is logged-in, as determined by examining utmpx(5).
