I can confirm the issue. Thin clients look fine, fat clients don't.

Title:
Screen Lock does not prompt for password
Status in Unity:
Confirmed
Status in “unity” package in Ubuntu:
Confirmed
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.
