[[!meta title="krb5-auth-dialog GNOME Kerberos Authentication Dialog"]]
Krb5-auth-dialog is a tray applet for the [GNOME](http://gnome.org) Desktop that monitors [Kerberos](http://web.mit.edu/kerberos/www/) tickets.
[[!toc ]]
## Features
* It can alert the user via [notifications](http://www.galago-project.org/specs/notification/) when the ticket is about to expire.
* Tickets can be acquired by clicking on the tray icon.
* If the notification daemon supports persistence (like in [GNOME 3][2]) the tray icon can be avoided and resident notifications are used.
* Current tickets in the credential cache can be listed.
* It can be extended using [plugins](http://git.gnome.org/browse/krb5-auth-dialog/tree/plugins/ka-plugin-dummy.c). This can be used to extend krb5-auth-dialog to e.g. handle things like [kx509](https://bugzilla.gnome.org/show_bug.cgi?id=347034).
* These plugins are currently available:
* afs: a plugin to acquire AFS tickets
* dummy: a sample plugin printing to the console
* pam: a plugin invoking the pam stack
* A [DBus][] API for applications to acquire a Kerberos ticket and to remove the credentials cache is provided.
* [DBus][] signals notify applications about acquired, renewed and expired tickets.
* It supports PKinit (e.g. via SmartCard) when built against [Heimdal](http://h5l.org).
## Source Code
The source code is available and browseable via [GNOMEs GIT](http://git.gnome.org/cgit/krb5-auth-dialog/):
git clone git://git.gnome.org/krb5-auth-dialog
## Releases
Releases are availale from [download.gnome.org](http://download.gnome.org/sources/krb5-auth-dialog/). The current stable release is [3.8.0](http://download.gnome.org/sources/krb5-auth-dialog/3.8/).
## Debian Packages
Debian packges are available from [debian.org](http://packages.debian.org/search?keywords=krb5-auth-dialog).
## Screenshots
The tray icon can be seen [here](http://honk.sigxcpu.org/con/krb5_auth_dialog_updates.html) and [here](http://honk.sigxcpu.org/con/krb5_auth_dialog__new_icon.html). Below are pictures of the password and preferences dialogs:
<div class="screenshots">
[[!img pwdialog.png size="x150" alt="password dialog"]]
[[!img prefs.png size="x150" alt="preferences dialog"]]
</div>
The notifications under [GNOME 3][2] look like this:
<div class="screenshots">
[[!img notify-valid.png alt="valid ticket notification"]]
[[!img notify-expired.png alt="expired ticket notification"]]
</div>
## Plugins
There are currently three plugins available:
* afs - call aklog or afslog to aquire AFS tickets
* pam - invoke PAM modules
* dummy - example plugin
These plugins can be activated using a [key in GSettings][0]
## DBus API
* There's a DBus API to acquire Kerberos ticktes. See the [examples][1]. [virt-manager][] is using this and [here](http://honk.sigxcpu.org/unsorted-patches/offlineimap_acquire-tgt.diff)'s a patch for [offlineimap][].
* DBus signals notify about acquired, renewed or expired tickets. This can be used to e.g. run [aklog](http://docs.openafs.org/Reference/1/aklog.html) via this [example](http://git.gnome.org/browse/krb5-auth-dialog/commit/?id=c374a7f8dbe6ef40c65752e3f35635d50d6b9260).
## Todo
* Add gnome keyring support ([567701](http://bugzilla.gnome.org/show_bug.cgi?id=567701))
* Remove all wakeups, rely on our gio watch of the ticket cache
* Add cache version, etc. to ticket dialog
* Add fast principal switching
* Make more applications use the DBUS API to make Kerberos a smooth experience on the desktop:
* [libsoup](https://bugzilla.gnome.org/show_bug.cgi?id=587145) - used by nautilus and evolution for calendars
* [Thunderbird](https://bugzilla.mozilla.org/show_bug.cgi?id=524698)
* Evolution IMAP and SMTP
* ssh client
### GNOME 3 Readiness
* krb5-auth-dialog uses persistent notifications instead of a tray icon
* Settings were moved from a stand alone dialog into the gnome-control-center panel
### GNOME Goals
Status of current [Gnome goals][] in krb5-auth-dialog:
* [Deprecated GLib symbols][] - done
* [Deprecated Gtk+ symbols][] - done
* [Clean up GLib and GTK+ includes][] - done
* [Use GtkBuilder instead of libglade][] - done
* [Use a correct Generic Name][] - done
* [Use GSeal][] - done
* [Migrate to GSettings / dconf][] - done
* [Migrate to GDBus][] - done
