User-1 - Logs in, Starts the VPN & Connects.
User-1 - Logs out of the machine.
User-2 - Now logs in to the machine
User-2 is already connected to the VPN.
The VPN did not disconnect when User-1 logged out, so User-2 is automatically connected to the network.
I need to force the VPN to disconnect when the user logs out, for security.
