Subject: [PATCH 1/2] gdm: add AuthList control
Ultimately, we want to add support for GDM's new ChoiceList
PAM extension. That extension allows PAM modules to present
a list of choices to the user. Before we can support that
extension, however, we need to have a list control in the
login-screen/unlock screen. This commit adds that control.
For the most part, it's a copy-and-paste of the gdm userlist,
but with less features. It lacks API specific to the users,
lacks the built in timed login indicator, etc. It does feature
a label heading.
