Allow LoginWindow only for some users on Mac OS X Server

Looking for the way to disallow regular users to login via VNC or Apple Remote Desktop?

- Open Server Admin in /Applications/Server/
- Connect to and select your server.
- 10.5 Server: select Settings -> Access
- 10.7 Server: select Access
- Then select Services -> For selected services below -> Login Window.
- Then select Allow only users and groups below on the right, and add yourself and whoever else you want to grant access.

10.5 Server:


10.7 Server:


I have no idea if this method is still present in 10.8 or 10.9 server.
