I am trying to get this setup and everything works fine with a local username and password but not when I try link it to Active Directory. Just gives me OpenVPN: Active Directory pre-authentication failed (K1:N255)
Is there a guide or something I can use for the setup.
Also how do I setup the VPN to use DNS records for our public static IP’s? Just in case we change them in future I do not want to be setting up a 100 VPN endpoints.
