Adding a Windows Azure Website to a local domain?

Hello Community,

I'm currently developing a solution for a client and we're looking into deploying their application in a Azure Website instance.  That is, a ASP.NET WebAPI application that will deploy to:

http://*applicationame*.azurewebsites.net

I'm looking to secure this application with Windows Authentication, and wanting to know how to add this Website instance so that it is a part of the client's Windows Domain.  Is this possible?

It appears this is possible with Cloud Services as outlined here:

Is this possible with Azure Websites?

Thank you,

Michael
