Extending the schema of AD is a serious thing. It's not just a matter of
writing the code. You need to do some serious thinking about deployment and
administration issues ranging from security to disaster recovery. I
recommend starting with Chapter 9 of the book
http://www.microsoft.com/mspress/book.... It's not a .NET book so the
code samples are in C++ but it covers the important concepts.

As far as .NET code, here's an old newsgroup posting with a C# sample...
