Spring Security Retrieving authenticated user after receiving SAML from Microsoft Intra ID Saml2AuthenticatedPrincipal object is always null with spring 3

To Reproduce Steps to reproduce the behavior.

Expected behavior non null object 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.
