Status in unity package in Ubuntu: Fix Released Status in unity source package in Xenial: In Progress Status in unity source package in Bionic: In Progress Status in unity source package in Cosmic: Fix Released Bug description: [Impact] After locking, the login screen shows the message "Authentication Failure" and the user must click "Switch to greeter" to continue. This SRU fixes the regression introduced in 44e6022, which causes the lock screen to start failing when session switching is involved. This can happen when you unlock the session from LightDM or from the CLI. We need to cancel the authentication in order to ensure that the next one does not fail. [Test Case] On a system with LightDM and more than one local user ("bob" and "alice"): 1. Login under bob. 2. Via upper-right menu switch to "alice". 3. On greeter screen select "alice", login under alice. 4. Logout, return to greeter screen. 5. Select bob (already logged in). Enter password. 6. Lock screen. [Other Info] This happens mostly after switching user sessions.
