SAML Trust Configuration in SAP BTP

SAML Trust Configuration in SAP BTP is the setup that establishes a trusted relationship between SAP BTP and a SAML-based Identity Provider (IdP), enabling federated authentication for users. Developers use it to register an external IdP — such as SAP SuccessFactors — with the UAA (User Account and Authentication service) so that users can authenticate through that IdP when accessing BTP-hosted applications. SAP BTP also supports restoring a SAML trust configuration if a custom IdP configuration is accidentally replaced or lost. The process involves exchanging SAML metadata between SAP BTP and the IdP, as described in Establish Trust and Federation with UAA Using Any SAML Identity Provider.
