title: How to add Azure AD Authentication to Existing ASP.NET MVC Application?
body: <p>I have an existing ASP.NET MVC application using Visual Studio 2013. I followed this walk-through but it only concerns itself with a new greenfield project while selecting <strong>Change Authentication</strong> in project template: <a href="http://www.asp.net/identity/overview/getting-started/developing-aspnet-apps-with-windows-azure-active-directory">Developing ASP.NET Apps with Windows Azure Active Directory</a></p>
  
  <p>I am not interested in using OWIN and OpenID Connect Katana modules as these components have lots of issues so I am waiting for that technology to mature and render out all the current problems. </p>
  
  <p>I aim is understand how to manually add all the components and configuration to my existing ASP.NET MVC application to achieve the same Azure AD authentication model in Rick Anderson's article.</p>
