Public bug reported: I am using LTSP fat clients, created with:
$ sudo ltsp-build-image --arch amd64 --fat-client-desktop ubuntu-desktop LTSP server has sssd authentication utilizing pam and ldap. Users can log in without issue and the home folder is available. Everything works as expected except for screen locking. When locking the screen, the displays first go blank and the monitor goes to sleep. Then if i move the mouse or press a keystroke, They go black but the mouse is visible. Once I move the mouse or strike a key the second time, everything comes back up without password prompt. However, password prompt is enabled in "Brightness & Lock" The client hardware is an Intel NUC D34010WYK Also maybe related, there seems to be no system tray. No clock or username/logout buttons. I am using Ctrl + Alt + L to lock the screen. (See attached screenshot) This is a security vulnerability and I can not make the new 14.04 image available as fat clients, since they users cannot lock their workstation. ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Screenshot of desktop without system tray" https://bugs.launchpad.net/bugs/1316320/+attachment/4105904/+files/Screenshot%20from%202014-05-05%2017%3A21%3A05.png ** Information type changed from Private Security to Public ** Description changed: I am using LTSP fat clients, created with: $ sudo ltsp-build-image --arch amd64 --fat-client-desktop ubuntu-desktop - LTSP has sssd authentication utilizing pam and ldap.
