title: Setup Microsoft Azure SAML 2.0 SSO on an IIS website
body: <p>I have built a web-based application hosted on IIS, but my client wants it to use Azure for SSO. I've read through some documentation, but I am rather lost. I haven't found any documentation that gives me a clear set of instructions on how to integrate SSO on an IIS website which has no current connection with Azure or anything else like that. Do I need to purchase a license from Microsoft to do this? I have some of the details, such as the XML certificate file for my client. But I really don't know where to start.</p>
