Since the switch-user functionality is provided purely by the Session Indicator, it's the Session Indicator that needs to properly handle the gsettings even in lockscreen mode.

Matching subscriptions: dx-packages, dx-packages https://bugs.launchpad.net/bugs/1327384 Title: unity-panel-service --lockscreen-mode does not provide a way to disable "Switch User" Status in “indicator-session” package in Ubuntu: New Status in “unity” package in Ubuntu: New Bug description: 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.
