I am tasked with setting up SAML 2.0 Single Sign On via the Sustainsys (Kentor) library for the project I am currently working on. Here is the documentation I have been following. The website is a webforms application so I am using the HTTPModule portion of the Sustainsys library. I have configured my IDP (Okta) to send the SAML 2.0 assertions to the website which the documentation proclaims the Endpoint to be /Saml or /Saml/Acs. The site is a Kentico CMS website and the CMS offers an API for authenticating the user using their username as the parameter to authenticate them.
The part I am having a hard time figuring out is, once the assertion has been passed Sustainsys how do I then access that data within my application so that I may view the claims, extract the username, and authenticate the user? The documentation describes how to configure the system, but it doesn't seem to describe how to use it..
The library extracts all the attributes from the SAML2 Assertion and creates claims out of them. The HttpModule then calls the SessionAuthenticationModule (which you need to have loaded) to create a cookie to persist the info.
From within your application, you just have to access HttpContext.Current.User.
