title: Spring Security 3.1 using Active Directory
body: <p>I'm trying to secure my Spring 3.1 web app with Spring Security 3.1, and I need to use Active Directory for user authentication.
  However, I cant seem to find the complete configuration steps. I tried different bits of suggestions but they didn't work for me.</p>
  
  <p>What are the complete steps of configuration to enable a Spring 3.1 web app to use Spring Security 3.1 with Active Directory?</p>
