Federation
Authentication Request
An Authentication Request is the message by which a service provider asks an identity provider to authenticate a user.
Definition
An Authentication Request is the federated protocol message used to initiate a login transaction by redirecting or referring the user to an identity provider. It expresses the service provider's request for authentication and may carry expectations about binding, requested authentication context, or return endpoint.
