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.
