Running Duo Proxy 2.0 on ADFS Proxy Server to enable Duo MFA. when trying to authenticate via ADFS Proxy in to our Dynamics CRM getting an error System.Exception: Unable to parse username from SAML token:
The Duo ADFS 2.x integration isn’t compatible with applications sending encrypted assertions, like Dynamics. This issue is not seen on ADFS 3+ where MS implemented native support for MFA plugins.
