OpenVPN simultaneous limiting client connections?

Hey Guys,

New here, But have been doing as much as I can in terms of reading and can't for the life of me find the answer <insert multiple amounts of google-fu and forum searches>

Basically I am running the latest OpenVPN access server RPM (Centos 7). It works as expected out of the box I can connect etc (I was running the CLI version before).

Basically my configuration allows a single user to have many concurrent connections at a time. So basically the duplicate-cn flag is enabled. What I am wanting to do is basically limit this to 5 clients per user ie.

user: has 2 phones, 2 tablets and computer. if they wish to connect another device it will not allow them unless they disconnect one of their clients/devices.

if possible I'd rather do this WITHOUT having to create a separate certificate for each user.

TL;DR basically have duplicate-cn like functionality but limit to 5 connections at a time per user.

I'm not sure what logs/configs you guys would need also speaking of if I modify the conf files in access server will I break anything?

Cheers
