What is an IdP in the context of federating Oracle Cloud Infrastructure with external identity...

An Identity Provider (IdP) in OCI federation is a service that authenticates users and provides their identity credentials, such as Microsoft Entra ID or another SAML-compliant provider. It doesn’t merely call a service provider (Option A) or act as a protocol (Option B—e.g., SAML is the protocol, not the IdP). It’s also distinct from OCI’s internal resource management components (Option D), like IAM. OCI’s identity federation documentation defines the IdP’s role in enabling single sign-on (SSO) across clouds.
