This is THE book on Active Directory and LDAP programming in .NET. Why? Because it's the only book that covers System.DirectoryServices. This book contains a lot of tips & tricks and best practices when it comes to integrating Active Directory, ADAM and other LDAP stores in your enterprise applications. At least when you are using .NET 1.x or .NET 2.0. As I already mentioned in this post, .NET 3.5 introduces a new namespace that makes it more productive to enable LDAP stores in your applications.
This new namespace makes the contents of this book a little bit obsolete, but certainly not for .NET 1.x and .NET 2.0 applications. I did some minor LDAP programming before I've read this book. The impression I have now is that I was doing it all wrong! For the current project I'm working on, I'll be doing a fair amount of LDAP programming as we need to integrate Active Directory and a third-party LDAP store. I know one thing for sure. This book will be on my side while I'm developing this.
