Multiple OpenVPN servers - how to restrict availability of one server to local database group?

[NickyDoes]

I have multiple OpenVPN VPN servers configured. One server allows access to a particular internal subnet. For auth, I use pfSense's local database and have created a group with members. How can I restrict the one OpenVPN server access so only users of the special group are permitted to use that VPN server?

You have to use different CAs on each server. So only users, who owns a client certificate from a certain server, can connect.
