OAuth2+ OpenID Connect SSO

Question

I am trying to implement the OpenID Connect SSO as outlined in Nik Vahalik’s YouTube video and in Patrick Dawkins’ Tutorial. I have gone step by step through their implementation instructions as well on the documentation page (https://www.drupal.org/node/2274367).

I have the OAuth server running on one Drupal Instance. I have the client login setup on a different Drupal Instance. I have the sso.php located in the root of each Drupal instance.

When I click “Login with Generic” on the client site, I get an error that says “Not Found The requested URL /oauth2/authorize was not found on this server.” The URL bar shows this as its attempted destination: https://devcondrupal.genieve.com/oauth2/authorize?client_id=devdrupalclient&response_type=code&scope=openid%20email%20profile&redirect_uri=https%3A//devdrupal.genieve.com/%3Fq%3Dopenid-connect/generic&state=7a4e2dc4a66e3aa3b4531b5d523f6371

I am using self-signed SSL certificates on both the OAuth Server site and on the Client site.

I don’t know where to begin troubleshooting the issue as this is my first experience with OAuth / OpenID and there is not much information out there on the web (Drupal-wise).

Thanks for your help.

It turns out that "Clean URLs" need to be turned on for OpenID... I added "AllowOverride All" to the section under VirtualHost in my Apache config file. This allowed me to turn on Clean URLs and the error is now gone.
