SSL VPN authentication using only one Group on NPS

[Bhadresh Prajapati]

Our SSL VPN working with NPS ( windows server 2012 ) but now all AD users can authenticate to SSL VPN.

we want to allow only one user group on AD (NPS ) authorize / authenticate SSL VPN users.

can someone please share possible configuration

In NPS just add an additional restriction that users have to me a member of whatever AD group you want to use to control it.
