# &application; Manual

## Introduction

&app; is an applet for the `GNOME desktop` that monitors and refreshes your Kerberos ticket. It pops up reminders when the ticket is about to expire.

Once you have acquired a Kerberos ticket - be it via GDM or via the applet itself - the applet will handle the ticket's renewal until it expires. It can also be used to destroy (remove) the credential cache, to acquire a ticket with different options or to switch to another principal.

## Usage

&app; is usually started in GNOME startup, but you can manually start &app; by doing:

Command line

- Type `krb5-auth-dialog`, then press Return:

From now on &app; will display notifications when the status of your Kerberos tickets changes. If you want to get an overview of the current tickets just activate &app; by clicking on the notification or by starting it again as described above.

### Kerberos credentials valid
