IIS Authentication plugin for the Wordpress PHP blogging engine
This weekend, I was working on an MSDN magazine article and happened to install the Wordpress PHP blog app on IIS7. Of course, I used the latest FastCGI bits available in the box in in Windows Server 2008 Beta 3, and the latest Windows-optimized PHP 5.2.3 build from www.php.net. Long story short, I ended up writing a Wordpress plugin that allows Wordpress to use IIS authentication methods, including forms authentication.
