OpenVPN Dual Authentication (Certificate + Password)

[indevd]

Hi!
Just setup a OpenVpN server in a FreeNAS Jail and certificate authentication works like a charm. However, I was wondering whether it would make sense to also add username/password authentication on top of that.
Previously, before moving the OpenVPN server to FreeNAS, I was using Synology server and I had a double authentication with auth-user-pass and plugin (using the Radius built-in server) directives.

So the questions are:
1. Does the dual authentication make sense at all?
2. If it does, how to implement it in the FreeNAS jail? How would it be possible to use the FreeNAS user database or my Synology Radius server?

Thanks!
