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, the user cannot use Basic Authentication
- A partial workaround is available through a feature called partial org sso for App login.
- Users who have been assigned the permission "Manage Integration Tools --> Allow Admin to Access OData API through Basic Authentication" from the Manage Permission Roles can log in using a password into the SuccessFactors system, even if they are an SSO user(after enabling the partial SSO feature).
- Note: Basic Authentication should be used only by users who need administrative access for system-to-system data integration(In the SSO enabled instance).
