SAML 2.0 Trust and Federation Configuration

The concept name is not defined in the provided sources, and no specific SAP developer concept is identified in the supplied snippets beyond general references to SAML identity provider trust and federation on SAP Business Technology Platform. Based on the available sources, a SAML Identity Provider (IdP) is an external system that authenticates business users and asserts their identity to SAP BTP via the SAML protocol. Developers and administrators establish trust and federation with UAA using a SAML identity provider so that users can log on to BTP services through their organization's identity system. Federation attributes can be configured for default SAML federation to control how user attributes from the IdP are mapped to BTP business users.
