azure adfs & WCF sample

Hi,

I'm trying to test the use of Azure federated AD and I've followed the instructions inhttp://msdn.microsoft.com/en-us/library/jj161104(v=vs.110).aspx except I selected to use Windows Azure Active Directory rather than the local STS. I set this up in Azure AD (having previously successfully tested the asp.net authorization through Azure AD) and copied the STS metadata address as required.

Here's the thing. When I run the client and WCF app, it just goes to a CardSpace form with the error: incoming policy failed validation and that's the end of that. I've been hunting for days to find a solution but it's beaten me.

Any ideas?
