2505553 - Basic Authorization cannot be used in a SSO enabled Successfactors instance


  • Your Successfactors instance is Single Sign On(SSO) enabled
  • You are trying to authenticate on the API server using "Basic Authentication" with this user




  • When SSO is enabled, users cannot use Basic Auth.
  • A partial workaround is available through a feature called partial org sso for App login.
  • Users who have been assigned the permission "Admin Access to OData API" from the RBP system can log in using a password-based login, even if they are an SSO user.
  • Note: Basic Auth should be used only by users who need administrative access for system-to-system data integration.


  • Basic auth not allowed in SSO enabled instance
