Implement Active Directory in CE 5.2

I wan to integrate Microsoft Active Directory with Pentaho. I have one domain controller and two VMs (test machines) setup for this purpose. These two VMs or users are listed in the Active Directory (AD). My aim is to provide access to particular reports to particular users in PUC. For this, the administrator should be able to see the users listed in the AD. I found a link but it is for Pentaho CE 3.0. http://wiki.pentaho.com/display/Serv...1%29+2.x-3.0.x

Please help me with this requirement.
