Client Credentials Grant Flow

Server-to-server authentication using Oauth2 and the Client credentials grant flow may be supported using these steps. Other flows may also be supported in a similar flow. User-authentication using Oauth2 and OpendId is described here.

Please note that even though Oauth2 is standard, the naming conventions of all parameters may differ - these names worked using an Identity Server 4.
