ASP.NET Enterprise Single Sign-On with BlackBerry Smartphones

My article about single sign-on (SSO) using ASP.NET and BlackBerry devices was just published in the BlackBerry Developer Journal. If you're like me and prefer to read from paper instead of liquid crystals, there's a printable version, too. However, you're going to need to use the web version for copying code samples or to download the sample code in the Visual Studio solution.

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.
