Apache module mod_auth_openidc allows you to authenticate members using NATS as the OpenID Connect server

Installing mod_auth_openidc

Please ask your host to install the mod_auth_openidc apache module on your member area server(s) if not already installed. Here is a link to their releases. It would be best if they can use one of the install packages. If not, they can compile it from source. NATS OpenID Connect server supports mod_auth_openidc starting from version 2.2.0.

Member Area Configuration

  • You will need to make a vanity script inside your members area. This should be a completely blank script that servers no content. It is only needed for the inner works of the mod_auth_openidc apache module. The only requirement is that this script must be protected by the mod_auth_openidc apache module using either the <Directory> or the <Files> directives.
  • You can optionally make an error template and an unauthorized page so that you have better control of what your members see in case of errors. This will allow you to control the look and feel of those pages as well as provide members with help (like links back to the login page).
  • You might need to change the link to your members area. It will need to be a link to any script protected by the <Directory> or the <Files> directives other than the vanity script.
