Application Security on Azure Website

Hi,

I have developed an application which I have moved onto Azure.  My Azure instance was created through my Azure MSDN subscription.  I have followed this tutorial to setup authentication on my Website:

http://msdn.microsoft.com/en-us/library/windowsazure/dn151790.aspx

The only thing I could not complete was under the section "Create your directory".  The tutorial directs you to create a directory called "Litware".  However, I cannot do this, as I already had the "Default Directory" already created.  But I can follow all of the other steps.

When I goto the Website I created, I am challenged for a username and password.  First, I entered my Live ID (Microsoft Account) and I recieved the following error:

HTTP Error Code:  400
Message:  ACS50000: There was an error issuing a token.
Inner Message:  ACS20016: The domain of the logged in user does not match any allowed domain of this STS.

Then I created a new user on the "Default Directory" and tried that.  But I get the error message:

HTTP Error Code:  400
Message:  ACS20012: The request is not a valid WS-Federation protocol message.

I would appreciateany help!

Thanks,

John
