为什么我的MVC3网页没有向IIS Express发送Windows凭据？

Question

I have been struggling with getting Windows Authentication to work with my MVC3 application in development (VS 2010 SP1), with no real luck so far. I am running XP on my dev machine (no money until next year for an upgrade), if that makes a difference. I should also mention I am using IIS Express as the default web development server from VS 2010.

I started with an empty MVC3 app awhile back, as I didn't have the Intranet template available from the VS menu until I upgraded the MVC3 tools yesterday (OK, I was a little slow). Once I installed and inspected that template, I added a reference to DirectoryServices to my project and added the bit of code that displays the current logged-on user in the upper right corner of the page. According to the graphics, it should now say "Welcome PCE\\dnewman!"

I followed the excellent instructions in this post: IIS Express Windows Authentication and did make some headway. However, I now get the 401.2 error from IIS Express, telling me I am not authorized...

So, I went in to my project properties and set Anonymous Authentication to Enabled. Now I can access the web page, but what I see in the upper right corner of my page is "Welcome !" -- no username.

I tried this with both IE and Firefox, with the same result. What the $#^&! am I missing here? It seems I am not logged in to Windows!! Where do I need to start looking for the problem?

At a previous employer a couple of years back, I wrote a Windows Forms app that authenticated the user with their Windows logon credentials. In that case, I had to take special care to both send the credentials and then to explicitly authenticate them on the service end. Is there something I have to do to make the browser include credentials with every GET or POST?

By request, here's the contents of my web.config, with apologies for all the Glimpse config stuff.

I am more than willing to divulge more details as needed, but I really don't even know where to start looking. Every post or article I can find seems to assume this part just happens as part of the Windows/MVC3/ASP.NET setup.

Thanks, Dave

If you follow all the recommendations in the referenced post, you'll end up with a non-working mess, like I did. Each answer has its own merit, but applying all of them only ends in frustration.

The post from Microsoft that answered all questions and got me working is here: How to Create an Intranet Site Using ASP.NET MVC

Save this link, it's golden...

I also found the "Add Deployable Dependencies" option can break Windows authentication. If I selected the "ASP.NET Web Pages with Razor syntax" option in the "Add Deployable Dependencies" dialog box, it immediately broke Windows authentication and seemed to go back to forms authentication -- I got a 404 error "The resource cannot be found" looking for /Account/Login. I didn't have to deploy it, just selecting that option broke it. The only way to fix it then is to start over. I was unable to remove enough of anything to get it to start working again, and I was unable to determine what change was made that caused this behavior.

This blog post saved the day: How to Deploy an ASP.NET MVC 3 App to Web Hosting with "\\bin Deployment" - it shows which assemblies are needed and how to get them included with your web app when you deploy it WITHOUT using the "Add Deployable Dependencies" nonsense.

I hope this saves somebody the hours I spent trying to get it all to work.
