• The IDP management service will accept objects from both the new and existing classes.
• Added a new class to manage the endpoint configuration of the custom authentication extension.
• Enhanced the service layer to accommodate endpoint configuration management for user-defined federated authenticators.
• Improved unit tests to cover the new code changes.
