I’m trying to make the IdP initiated flow from an external SAML connection, but whenever it’s initiated, it fails with the following error:
access_denied: The InResponseTo attribute does not match the id in the AuthNRequest
The current setup comprises from djangosaml2idp, acting as my external IdP,
connected to Auth0 through an Enterprise connection.
Everything works when navigating into the app, getting redirected to the IdP login and back, but whenever I try to initiate the process from the IdP side, it fails.
