Every example of ovpn-server setup I have seen on the Internet always uses /ppp secret user+password. But what about client certificate authentication? I do not see a single working example where an OpenVPN client using certificates has been able to login to a RouterOS OpenVPN server and authenticate using the certificate.

Does anyone have an example? I can't make it work here. I'm starting to think this feature has never worked on any version of RouterOS.
