Mod auth openidc

In my eyes, that felt like something that should be separate from any given app or back end API, so in my case I use mod_auth_openidc: https://github.com/OpenIDC/mod_auth_openidc https://github.com/OpenIDC/mod_auth_openidc with Keycloak: https://www.keycloak.org/ https://www.keycloak.org/ My back end/app just gets a few headers that say who an authenticated user is, if they are logged in.
