I am currently using WSS3 and use SharePoint to host my custom ASP.Net web applications. The URLs for the site are in the format http://fqdn/aspsite. If I am not currently signed in, I get prompted to log in.
I am configuring SharePoint 2013 and want it to work in the same way. I am using Claims authentication via SAML/ADFS. I am stuck on trying to get the authentication to work. I have tried setting up my ADFS with Forms authentication and setting the ASP.Net site to use the sign in URL from the ADFS site, but it adds a parameter for the return URL at the end. Is there a way to get this to work without rewriting my current ASP.net applications?
