Configuring Tomcat to authenticate using Windows Active Directory

Question

What is the best way to configure Tomcat 5.5 or later to authenticate users from Windows Active Directory?

Answer 1

"Welcome to the SPNEGO SourceForge project Integrated Windows Authentication in Java

The intent of this project is to provide an alternative library (.jar file) that application servers (like Tomcat) can use as the means for authenticating clients (like web browsers).

If your organization is running Active Directory (AD) and all of your web applications go through Microsoft's Internet Information Services (IIS), and IIS has Integrated Windows Authentication enabled, and everyone in your organization is using Internet Explorer (IE), then this project may not be of any interest to you."
