macOS has a privilege that can be granted to any user that will allow that user to unlock active users sessions.
Disabling the admins and/or users ability to log into another users active and locked session prevents unauthorized persons from viewing potentially sensitive and/or personal information.
While Fast user switching is a workaround for some lab environments especially where there is even less of an expectation of privacy this setting change may impact some maintenance workflows
Fix:
sudo security authorizationdb write system.login.screensaver use-login-window-ui
Parameter:
[yes/no]
Technical Mechanism:
sudo security authorizationdb write system.login.screensaver use-login-window-ui
