Guide to redirecting SAML SSO form-based authentication using Ajax

Hey there, I'm encountering a challenge with SAML SSO POST binding in the context of a protected Web application that includes Ajax script. Following the initial authentication process, which is managed by the browser, the Ajax code within the Web application successfully retrieves data from the server. However, issues arise when the security session expires and the service provider (SP) sends a SAMLRequest back to the identity provider (IdP) via SAML SSO POST using a form with auto submit. As the response returns with a code 200, the form containing the SAMLRequest ends up triggering an unexpected Ajax callback that isn't equipped to handle it.

So, here's my query:

  1. Is there a method for the Ajax callback code to communicate to the browser that it should refrain from processing this particular response and let the browser manage it conventionally?

  2. If not, how can I replicate the behavior of the browser, which simply submits the pre-filled form automatically?

Thank you, Gang

Answer №1

When dealing with WIF and WS-Federation integration for SSO IdP in a web application that heavily uses AJAX, one common issue arises. The Microsoft Identity Model processes SAML tokens and creates FedAuth cookies to handle session timeout values. Typically, the maximum session lifetime is determined by adding the clock skew and the SAML assertion lifetime, which is usually around 10 minutes. Once the maximum session lifetime elapses, WIF, on behalf of the SP web application, will generate a new SAML token using the WS-FED passive browser profile. However, when the web browser action does not trigger a full form post (like in AJAX), the request may fail, leading users to think the application has stalled. In reality, the application is still active, but users may need to manually refresh the browser to resume processing.

To address this issue, a practical solution I have implemented involves customizing the Microsoft Identity Model DLL to calculate a longer maximum session timeout than just the sum of SAML assertion lifetime and clock skew. By setting a specific value in the web.config representing the maximum session timeout (e.g., 4 hours), the AJAX problem caused by expired FedAuth cookies can be avoided effectively.

An alternative approach to tackle this challenge is to periodically retrieve SAML assertions from the SSO IdP. This method requires implementing sliding logic in a custom DLL to extend the capabilities of the Microsoft Identity Model.
