I am trying to configure ADSS vpn to enable password sync. We currently are using the Sophos Authenticator with our user VPN and want to use the same VPN for the password sync. Sophos uses OpenVPN and I can configure it to talk to our server, but it comes back with an Auth Failure message.
My guess is that our VPN requires 2FA and that is not getting activated when ADSS connects.
So, am I totally off-base or is there something else I need to do to make this happen?
