Some time ago I wrote a simple web application which runs on Microsoft Azure and uses Azure Active Directory for authentication. The application is used constantly and has proved reliable; however yesterday it stopped working. A quick debug session showed that the problem was an Azure AD permissions error.
In order to use Azure AD,

I have recently completed (if applications are ever completed) an application which runs on Microsoft’s Azure platform. I used lots of Microsoft technology:

Regular readers will know that I am working on a simple (I thought) ASP.NET MVC application which is hosted on Azure and uses Azure Blob Storage.
