Describe the bug

Sample

A link to a GitHub repository with a minimal, reproducible sample.

Reports that include a sample will take priority over reports that do not.
At times, we may require a sample, so it is good to try and include a sample up front.

Sorry that you are having trouble, @doukhahmed. Can you please post the contents of the HTTP response from the IdP that contains the SAML assertion? Please include the body, headers, and URI.
