Windows Azure Active Directory community forums.
As part of our launch today, we have updated all our documentation to help you better use our platform. We took your feedback during the Preview period and have released all new samples, walk-throughs, and API documentation. We have also consolidated all of our documentation in one area, MSDN. We are no longer spread across WindowsAzure.com and MSDN for different topics.
We will be releasing more samples as the weeks progress.
Check out the documentation here: http://msdn.microsoft.com/en-us/library/windowsazure/jj673460.aspx
As always, let us know what issues you find in the forums and feedback mechanism in the documentation.
