ASP.NET Enterprise Single Sign-On with BlackBerry Smartphones

Update 7/27/13: BlackBerry has removed the developer journal from their web site (it's quite old by now), but for the sake of removing broken links and keeping this here for sentimental reasons, the download links are below.
My article about single sign-on (SSO) using ASP.NET and BlackBerry devices was just published in the August 2008 BlackBerry Developer Journal.

I was able to work a lot of concepts into the article, the following being a small sample of the variety.

• Cookie authentication
• Kerberos S4U2Self implementation
• Custom .NET configuration section
• Application of the Page Controller and Intercepting Filter (and why it's so cool for IIS 7) architecture patterns

One of the cool takeaways included in the sample code is a method in C# that simulates ASP.NET's Active Directory authorization check.
Writing is so much more time consuming than I originally imagined. It was definitely a learning process. I now have much more of an appreciation for those that set out to write an entire book.
