I am using a Service Provider initiated call that redirects to the Identity Provider. Once the Identity Provider authenticates the user, it generates a SAML response and uses HTTP POST to send the information to the ACS URL.
The error that the Proxy Audit log shows is that the SAML POST request format is invalid. I've turned log levels to DEBUG, but there is no additional information as to the particular format the ACS is looking for.
How does Qlik determine that the SAML response format is invalid? Is there a standard template/format Qlik is looking for? Or is there any additional debugging information I can use to dig deeper as to why this is failing?
I have attached the SAML response that HTTP POST is sending to the ACS.
