Hi, my name is Roman Konicek and I would like to welcome you to my knowledge base article series on claims-based authentication. Let me give you a bit of an overview of some of the things we are going to cover in this series. I want to start by briefly talking about how to prepare a virtual environment. The second thing I would like to focus on is how to configure your environment to use claims-based authentication—in this specific case we are going to use Active Directory Federation Services (AD FS). Next, I want to discuss how to configure your Kentico application to use the claims-based authentication. In the last part, we are going to look at the most common issues when you are using claims-based authentication in Kentico. So let’s go and have a look at all of that.
