Kerberos Authentication Dialog
Tray applet for reauthenticating kerberos tickets
Kerberos Authentication allows you to list your current Kerberos tickets, and to request a new ticket (authenticate to the Kerberos Server). It also notifies you when your Kerberos credentials are about to expire and renews your ticket automatically if possible.
This is useful if you need to authenticate to a Kerberos Server (KDC) after your login to the desktop (e.g. on a mobile device).
krb5-auth-dialog is a simple tray applet that monitors kerberos tickets. It pops up reminders when the ticket is about to expire. Tickets can be refreshed at any time by clicking on the tray icon. It can also operate in "classic mode" as a simple dialog without any trayicon. . It features ticket autorenewal and supports pkinit.
