As most people will notice, by default the OpenVPN Access Server comes with a self-signed SSL/TLS web certificate. This leads to an ominous warning when first accessing the web interface. For technical reasons it is not possible to ensure that the Access Server starts out with a trusted web certificate so that this warning does not occur. Steps will have to be taken after installation to provide the Access Server with a valid web certificate. We have a guide available that explains how to install a signed web SSL/TLS certificate in the OpenVPN Access Server's web services.
