Taking inspiration from Kim Cameron and how he CardSpace-enabled WordPress, I did the same with DasBlog 1.9.6264.0. casadehambone.com now supports logging into the administrative account using Windows CardSpace allowing me to throw the use of passwords to the wind!
The great thing is that it only took minor changes to three source files and the introduction of one new configuration option each to site.config and siteSecurity.config. I have a little more work before me to make configuration just a tad easier, but the great thing is that this works really well.
I owe special thanks to Clemens Vasters who suggested this morning that the proper "hack" to get this working was to build DasBlog with Visual Studio 2005 and the Visual Studio 2005 Web Application Project add-on. DasBlog built out-of-the-box without issue, making the integration of TokenProcessor.cs to decrypt the SAML token a piece of cake.
If you haven't looked at Windows CardSpace yet, head on over to cardspace.netfx3.com and start reading. Now that Windows Internet Explorer 7.0 is released and Release Candidate 1 of .NET Framework 3.0 is available, you'll find the mainstream barriers to adoption are quickly eroding.
