The Sonicwall will load all groups within the containers you’ve configured it to look for them in and display them. Select the group you just created for your VPN users and click the Save selected button:
… and that’s it! Once the user starts their VPN client, they’ll authenticate with their normal Active Directory username and password and they’ll be granted access to whatever subnets you’ve specified.
