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 you be supplied notice of ticket expiration—through terminal, mail, or syslog —or to renew the TGT.
