I am trying to setup a SonicWall SSL VPN box to use Active Directory Auth. I have followed this guide - Portal_Tab_Configuration_Task_List

When i go into the local groups there is no tab to add the Active Directory groups like i have seen on the SSL VPN 4000 boxes.

The Server is a Server 2008 Domain, this network has never had the SSL VPN box on before.

Any advice is appreciated.
