3.1.1 Abstract Data Model

The client role is expected to be aware of the relying party or resource identifier of the resource server if it requests authorization for a particular resource. The client role sends this value to the AD FS server using the resource query string parameter ([MS-OAPX] section 2.2.2.1).

The client role is also expected to be aware of its own client identifier and all relevant client authentication information if it is a confidential client.
