Raw Blame History

From deb35ed74342b05be7cd45c458a06b98c7a4d1ac Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use secrets service for cups auth_info
When a printer requires auth_info (e.g. a printer connected
over the samba protocol) it is now possible to save the
credentials necessary for printing if a secrets service
is available over dbus.
The auth_info is then stored / loaded from the default
collection of that secrets service.
If no such service is available the user is not shown
the option to remember the password and the behavior
remains the same as before.
