title: Help Required on track active directory changes
body: <p>I am going to write a small software to track active directory changes. I need an expert opinion from you. I want to display information about What ( with before and after values), When, Where and Who of any change in AD. 
  I am going to implement this by one of the following way
  1. Change Notification Control
  2. DirSync Control</p>
  
  <p>Both of these method give us the attribute that are changed and we can compare new values with some dump in SQL Server to get old values.</p>
  
  <p>My problem is how can I find “Who” has made this change. I have tried but there is no attribute “LastModifiedBy” in active directory. Please give your opinion how can I track who has made this change.</p>
