After a really long wait, I found that the process of Adding Sign-On to Your Web Application Using Windows Azure AD has finally reached the level I would call "developer friendly. Finally all seems to be in sync: VS 2012, .NET 4.5 with integrated WIF, the Identity and Access tool VSIX ...
With a great joy, I followed the tutorial at http://msdn.microsoft.com/library/windowsazure/dn151790.aspx -- all the way until the end, when I tried to run the application being developed and configured in this article. I was properly authenticated by WAAD and asked to change my password. That went fine, and I was re-authenticated again, entered the new password and instead of seeing the application's welcome message I got:
An error occurred while processing your request.HTTP Error Code: 400
Message: ACS50000: There was an error issuing a token.
Inner Message: ACS50001: Relying party with identifier 'https://er.congral.net/' was not found.

This indicates how the WAAD failed to return back to my app, registered as:
Based on the APP ID URI I set, I do not understand the error message I got.
Can anyone shed some light here, please?
