Cause for Error: This error is displayed when IdP returns a status code other than SUCCESS.
The following are some of the common Status Code errors that you might encounter:
- Requester: The IDP sends this status code when it doesn’t like the SAML request.
For example: The IDP was expecting a signed request but it received an unsigned one.
- Responder: The IDP side of configuration is not correct.
For example: The ACS URL is not properly configured at the IDP end.
- AuthnFailed: Some IDPs send this status code if the signature verification of the SAML Request fails.
