    1. Name
    2. Single Sign-On Endpoint (HTTP Redirect)
    3. Single Logout URL (HTTP Redirect)
    4. Signing Certificate ( Insert as Text)

These fields would be used to add your SAP Cloud Platform Identity Service as a trusted identity provider in SAP Cloud Platform Open Connectors.

  • Navigate to your SAP Cloud Platform Open Connectors account, select the tab Security-> Identity -> Application Identity Provider. Select Add Trusted Identity Provider option.

Select true from the Strict Mode drop down.
  • Select Save after all the values are provided.
