Title:
  Screen Lock does not prompt for password

Status in Unity:

Status in “unity” package in Ubuntu:

Bug description:
  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.
