Turning off the session is just a brute force way of outright preventing all reuse of the results.</p> <p style="margin: 10px 0 0">Secondly, the IdP already does all this for you automatically when it's configured with the right supportedPrincipals settings and when the results get built with the right AuthnContextClassRefPrincipal objects and there's a ton of control over that.</p> <p style="margin: 10px 0 0">No new features are needed, it's a configuration task.</p> <p style="margin: 10px 0 0">It is not simple to do at times because it often depends on the user and service and other factors, but we all face similar issues making MFA work, it's the same problem in the end.</p> <p style="margin: 10px 0 0">The problem I think is that I don't know that you're in a position to provide a deployment specific scenario to work through because all of this is a very local matter in the end, you have to have specifics to work through how it needs to be configured. There's no recipe to follow, just general designs and features that tend to be common across some deployments, but there are always local complications.</p> <p style="margin: 10px 0 0">But bottom line, the IdP will never issue a response if the combination of AuthenticationResults does not carry a Principal that satisfies a RequestedAuthnContext or essential ACR claim. It's hardwired to prevent that. So the scenario you mention is flat out banned automatically unless the IdP is misconfigured.</p> </td>
