Limit number of connections from one user

fandar

Hello,

I have openvpn server where I need to limit number of connections from one user with unique username..
for example.. user has 3 opened session to a server

CLIENT_LIST,testuser,xxx.xxx.xxx.xx:50025,10.186.35.10,1741,3887,Wed Sep 4 18:29:57 2013,1378285197
CLIENT_LIST,testuser,xxx.xxx.xxx.xx:55420,10.186.35.6,2362,4576,Wed Sep 4 18:27:49 2013,1378285069
CLIENT_LIST,testuser,xxx.xxx.xxx.xx:55420,10.186.35.12,3342,2556,Wed Sep 4 18:27:49 2013,1378285169

Now I want to limit the connections for one user (in this case testuser) to be max 2.

After that I will also need to limit connections on more servers.. for example I have three servers and I want limit a client with the same username to have only 2 connections on all servers..

Can you please help me with this? Or give me some way for possible solutions?

Thank You in advance
