Openvpn with username and password

Question

I have configure OpenVPN it is working fine. But I always need to import configuration and it has ca certificate, I enabled username and password authentication. But still I need to add this certificate.

How can I connect openvpn without certificate and configuration but only username and password.

Now when I import this file and use my userid and password it connect, but I want to connect openvpn client without importing this client file and only providing username and password.

Answer 1

There's a directive you can use in your server.conf, depending on your OpenVPN version.

• client-cert-not-required:

  Makes your VPN a less secure as the cert is not required to authenticate (deprecated).

• verify-client-cert none|optional|require:

  Using verify-client-cert none is the equivalent of the aforementioned option.
