Federation
IdP-Initiated Flow
An IdP-Initiated Flow is a federation flow where access starts from the identity provider side.
Definition
An IdP-Initiated Flow is a SAML access pattern in which the user begins from the identity provider, often through a dedicated URL or launch point, and is then sent to the service provider. In this model, the service provider receives the federated material after the user has already authenticated with the identity provider.
The Ariovis perspective
Federation is an architecture choice, not a product checkbox. Ariovis assesses protocols, trust relationships, application constraints and migration paths before defining the target.
