If you specified the reneg-sec option in the server configuration above, be sure to also include it in your client configuration file: reneg-sec 0 The auth-user-pass line in the client config will cause the OpenVPN client to prompt the user for an additional password (described in more detail below) to authenticate. Configure the ClientĮnsure that the following line is present in the OpenVPN client configuration file of all of your users: auth-user-pass Save the configuration file and restart the OpenVPN server for the changes to take effect. If your OpenVPN version is below 2.2, then you should instead set reneg-sec to a very large value. Old versions of OpenVPN may fail to connect with reneg-sec set to 0. Therefore, we recommend disabling reneg-sec by setting it to 0 in your server configuration file: reneg-sec 0 If your user's VPN client saves the password and automatically reauthenticates with it, this may cause issues with the user receiving unexpected push notifications or their client replaying a one-time passcode. This setting defaults to 3600 seconds, which means your users must reauthenticate every hour. This option will determine how often OpenVPN forces a renegotiation, thereby requiring the user to reauthenticate with Duo. We also recommend setting the reneg-sec option in the server configuration file.
