In the SAML framework, a relying party (the service provider) receives and accepts a SAML assertion issued by a SAML authority (the IdP). A relying party trust consists of identifiers, names, and rules that identify the service provider to the IdP. You must add a relying party trust on your IdP's application––this allows Address Manager to receive and accept SAML assertions issued by the IdP. For more information on how to configure Address Manager as a relying party, contact your IdP.
