duplicate-dn doesn't count &nbsp; (it doesn't even have an argument)<br />
<br />
duplicate-cn &nbsp;present in config means &nbsp;if several users logon with the same certificates that IS allowed.<br />
duplicate-cn not present of disabled in the config &nbsp;means each logon must be from a unique user...<br />

openVPN has no options for that.<br />
It either is 1 limit case or unlimitted case. &nbsp;No setting any arbitrary limit.<br />
<br />
So you can issue the user two logins. (2 certificates) which can only login once each.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
