Public bug reported:

Unity's screen locking mechanism does not respect any existing gsettings
having to do with disabling the "Switch User" functionality, nor does it
provide any way to do it natively.  Ideally, it would respect
org.gnome.desktop.lockdown, but I realize that's probably never going to
happen.

I was able to disable the "Switch User" functionality in the indicator
menu by setting "com.canonical.indicator.session user-show-menu false"
in gsettings, but the lockscreen mode of unity-panel-service does not
respect this.  gnome-screensaver provided a way to do this
(org.gnome.desktop.lockdown disable-user-switching true), so this is a
major regression for anyone attempting to use Ubuntu in a public
computing environment.

Steps to reproduce:

1) Start a unity session.
2) gsettings com.canonical.indicator.session user-show-menu false
3) Observe that "Switch User" disappears from the indicator menu.
4) Lock the screen.
5) Observe that "Switch User" is present on the indicator menu.
6) Be sad.
