Fix timed login when user list is disabled Resolves: #1940618
2021-04-13 15:36:13 +00:00

Subject: [PATCH] loginDialog: Allow timed login with disabled user list
At the moment the timed login feature is implemented in the user list.
If there's no user list, we don't show the indicator anywhere and
don't proceed with timed login.
This commit allows timed login to work when the user list is disabled.
It accomplishes this by putting the timed login indicator on the
auth prompt in that scenario.
