I have configured my Open VPN and generated the cert and also configuration file How can i create user id for the connection? I read something that it dont support open vpn client?

Opening, this is NOT about the AD7200, I could not choose any other option. What is this ? I want to discuss the AX11000, not the AD7200 TP Link Archer AX11000 Drops 5 Ghz AX mode with Samsung Note 10

Hoe could i setup different user id for OpenVPN ? I dont seem to find any option to do this? i m able to configure the openvpn server
