## Feedback

To report a bug or make a suggestion regarding this package or this manual, use GNOME's Bugzilla.

## 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:

The tray icon will indicate one of three states:

### Valid Kerberos ticket

You have a valid Kerberos ticket that can be used to authenticate to network services.

#### Valid Kerberos ticket

### Kerberos ticket expiring

The Kerberos ticket is about to expire but it can still be used to authenticate to network services.

#### Kerberos ticket expiring

### Kerberos ticket expired

Your Kerberos became invalid (e.g. expired). It can no longer be used to authenticate to network services. This is not a problem if the application that requires Kerberos knows how to request a new ticket via &application;. In case it doesn't you can just left click on the applet an reenter your password.

#### Kerberos ticket expired

## Notification Messages

When &app; has started, the following notifications may be displayed.

### Kerberos credentials valid

You just acquired a valid Kerberos ticket that can be used to authenticate to network services.

#### Notification when Kerberos credentials become valid

### Kerberos credentials expiring

Your Kerberos credentials are about to expire. You can left click on the tray applet to refresh them.

#### Notification when Kerberos credentials expiring

### Kerberos credentials expired

Your Kerberos credentials just expired. They can no longer be used to authenticate to network services.

#### Notification when Kerberos credentials expired

## Preferences

You can set preferences by selecting "Preferences" from the applets context menu or by selecting "Network Authentication" in the Control Center.
