We use a third party VPN client which connects to our network via a number of globally positioned VPN concentrators using RADIUS authentication. These VPN concentrators are RADIUS clients with shared secrets and currently forward RADIUS requests to a Linux
based RADIUS server but I want to migrate the RADIUS authentication process to Windows server 2012. The Linux LDAP DB is synced with AD so usernames and passwords are exactly the same in both.
I want to create an NPS policy that basically only allows users in a given security group VPN access to our network, can I do this?
