'Log off' menu should be shown for enterprise logins

The 'Log off' item in the user menu should when the machine is joined to a realm. It's very important for these guys to be able to log off, change users and so on. We don't know the full list of users that can log in in this case, so we certainly don't know that only one can log in. In addition even if only one enterprise user can log in, such enterprise deployments will want to make sure their users can log off. It's a normal part of the work flow.
good point
We have a setting now to force the log off menuitem
