Solutions

Based on a protocol selection of OpenID Connect or OAuth 2.0, the full solution is described in the Identity Model.

This is the definition in RFC 6749 The OAuth 2.0 Authorization Framework. In this case the authorization server is one end point in the Identifier or Attribute Provider.

  The authorization code is obtained by using an authorization server
  as an intermediary between the client and resource owner.  Instead of
  requesting authorization directly from the resource owner, the client
  directs the resource owner to an authorization server (via its
  User Agent as defined in [RFC 2616]), which in turn directs the
  resource owner back to the client with the authorization code.

Other protocols, like SAML 2.0 are also available.
