Continuing the discussion on DisplayTokens [LINK] :
A number of you have emailed me directly and some have commented publicly with some thoughtful insight and I thank you for that. Vittorio has written a very thoughtful and detailed response on his own blog [LINK].
Going back to my original question which was "Does the DisplayToken violate the First Law of Identity?" I am not convinced it does. What I think I am discovering is that the First Law of Identity is not necessarily enforced.

I have been following along with the Identity story for some time now.
Cardspace as an Identity selector supports two basic models;

Self-Issued Cards in which essentially you act as your own security token service and
Managed cards – in which a trusted third party acts as Identity Provider making assertions around your identity.

I have seen many examples leveraging self-issued cards but relatively few incorporating managed cards. There is a sample STS available on the http://cardspace.netfx3.com website but due to the complex nature of it I’ve found …

Setting up Infocard/ Cardspace Today I’m going to explain how to enable accepting CardSpace cards (formerly known as Infocards) on your website.

I am doing lot of work with Cardspace and Infocard.
If you are trying to get the Infocard Labs working from the Vista Beta2 release of Infocard (earlier this year) with the latest June CTP of the .NET framework you’ll find the code doesn’t work with the latest CTP. This is due to a number of breaking changes that were implemented in the latest CTP.
You’ll find a list of these here: Breaking changes.
I found the most important one was the change from System.ServiceModel.Identity to System.ServiceModel.EndpointIdentity.
That should keep all …
