In a bilateral trust agreement, the establishment of the trust agreement occurs directly between the federated parties, and the trust agreement is not managed or facilitated by a separate party. Bilateral trust agreements allow for a point-to-point connection to be established between organizations that wish to provide federated identity access to services. Bilateral connections can take many forms, including large enterprise applications with static contracts or subscriber-driven dynamic connections to previously unknown RPs. In all cases, the CSP, IdP, and RP directly manage their policies regarding the federated connection. Bilateral trust agreements conform to the stated requirements for all trust agreements. However, since these trust agreements do not involve additional parties, there are no additional normative requirements for their establishment and management, such as those mandated for multi-lateral trust agreements (see Sec. 3.5.2 ).
