What is OpenID Connect?

OpenID Connect (OIDC) is an authentication layer on top of OAuth 2.0. The specification can be found here.  The inSided Community OpenID Connect scheme supports Authorization Code Flow.

 

OpenID Connect flow representation

In order to understand how the OpenID Connect process integrates into the overall Community SSO architecture (i.e. Steps #1-3 in the diagram below) please see Single Sign-on (SSO): Getting Started.

  1. Community redirects User to the Authorization URL with GET by attaching Redirect Uri and Client ID.

  2. Server authenticates the User and obtains consent/authorization.

  3. Server sends the User back to the Community Redirect Uri by attaching Authorization Code.

  4. Community requests a response with ID Token and Access Token in JSON format at the Token URL with POST(application/x-www-form-urlencoded) by attaching Authorization Code, Client ID, Redirect Uri and Client Secret as parameters.

  5. Community receives a response that contains an ID Token and Access Token in the response body.

  6. Community validates the ID Token and retrieves the user subject identifier or sub (later id).

  7. If User Info URL is configured Community requests a response with Profile data in JSON format at the User Info URL with GET by attaching Access Token as Authorization Bearer header.

After retrieving the minimal required id or more complete Profile dataCommunity starts #Step 3 of Community Single Sign-on.

Redirect Uri is generated by Community automatically
