SAP Identity Authentication Service (IAS) Integration

The concept name is not defined in the provided sources, so a precise definition cannot be grounded solely in the available snippets. Based on the sources, an Identity Provider (IdP) user is a user account managed by an external identity provider — such as SAP Identity Authentication Service — that developers and business users use to authenticate and access SAP BTP services and environments, including the ABAP Environment Administration Launchpad. Developers can be assigned to identity provider user groups to manage access and permissions within an SAP BTP subaccount. Trust between the SAP BTP subaccount and the identity provider must be established to enable scenarios such as single sign-on across connected systems.
