OpenVPN 2.5 breaks "Allow Only User/Pass (without cert) Auth" option

[Igor Lidin]

Since OpenVPN 2.5 integration the openvpn server GUI option “Allow Only User/Pass (without cert) Auth” (advanced tab) is broken.

The OpenVPN server just fails to start if this option is checked (tested on Asus RT-AC3200).

Enabling this option generates the no-more-allowed keyword (client-cert-not-required) in openvpn server config.
