In a native application use case two OAuth clients are registered with SSO. The first client is the "native application" presenting user interfaces to the end-user. The second client is usually a web service or resource server providing API services to the native application. 

The native application wants to get an access token for calling the resource server API services. The resource server validates the access token it receives by calling the tokeninfo service. The tokeninfo service returns claims and attributes describing the authenticated user.
