Indicates if the logout screen presents all users or just users with the same name.
True, if all users are shown, otherwise false. Default value: false.
>When a user logs in, Sitecore checks if the maximum number of users has been reached (as specified in the license). If so, the logout user web page is shown allowing the user to logout a existing session.
This flags is the user is allowed to logout only sessions with the same name as the user, or all other sessions. For instance if the flag is false, the user "Andy" may only logout other sessions created by the user "Andy". If the flag is true, "Andy" can also logout sessions created by "Bob".
The name of the web.config setting is "AllowLogoutOfAllUsers".
