If you're encountering a 404 error while using PingFederate single sign-on (SSO), it is possible that the authentication request requires a signed assertion.
To reconfigure the signature policy:
-
Navigate to the Signature Policy tab in PingFederate and uncheck the Always Sign Assertion box.
By disabling the Always Sign Assertion setting, the authentication request will be able to proceed without requiring a signed assertion.
If you encounter any further issues or have questions, refer to the PingFederate documentation or reach out to our support team for assistance.
