        Then you're lost. You need the certificate to revoke it.

        The OpenVPN is configured to accept any user cert which is issued by the CA you've set, as long it isn't in the selected CRL.

        Possibly you can restore the cert from a backup.

            pfSense automatically saves config history:

            Possibly you can temporarily revert to a config where the cert still exists, use the cert manager to export it and the key and after revert back to the actual config.

                  After revoking the cert, the client can still connect?
                  Existing connections are not cut when adding the respective cert to the CRL.

                  Did you assing the CRL the server?

                        Just for my understanding.

                        If you're changing the users passwd in the user manager & kill the connection.
                        Would that not prevent the user to login again ?
                        If not , then what good is the uid/pwd ??

                        I'd still revoke the cert , if i needed to ban a user permaneltly.

                        But for a temporarily disable (enable) login , i had hoped to use the
                        User Expiration date.

                        Ie. a Consultant that would have 1 week access for this specific task , and might need access later on.

                          Sure, it does, when the server is in a "User auth" mode.

                          You can also revoke a user cert temporarily. After removing from the CRL it is accepted again by the server.

                          Also consider, when "Strict User-CN Matching" in the server settings is not checked it will be possible for a user to use another ones cert for authentication.
