Windows authentication in asp.net mvc 3 hosted on Windows Azure?

Question

I am migrating one ASP.NET MVC 3 intranet Website to the Windows Azure and DB to SQL Azure.

On Premises my site uses Windows Authentication to authenticate and authorize the user(By Placing AUTHORIZE attribute on controllers).

It would be very kind of you If you can let me know How to go about the same.Thank You In Advance !

Answer 1

You have two choices here:

1. Use federated authentication and something like ACSv2. This requires a bit of work to setup a relying party, install ADFS2, etc. However, it is the most robust and future proof option. It is a very good option.
2. Use something like Windows Azure Connect. That will bring Windows Authentication to the cloud by joining your running instances to your domain controller on-premises. In effect, you have something of a VPN between your cloud instances and your on-premises domain controller. There are some caveats to this model today (requires installing agent on DC for instance), but it would be from a 'just works' stand point, the easiest. Longer term, this is less attractive I believe than option #1.

You can get more details for each of these by checking out the Windows Azure Platform Training Kit.

I should also add that you have no option (today at least) of using Windows Authentication with SQL Azure. You must use SQL authentication there, so what I am talking about here only applies to the web site itself.
