Monitoring Active Directory events

Question

How can I programatically detect any changes that occur to Microsoft's Active Directory?

Answer 1

You can use LDAP as explained in this article.

Answer 2

You probably need to be a bit more specific. Do you want to detect changes to one or two objects? If so, @DSO's recommendation is a good one. If you want to be able to do regular imports of all changes DirSync is probably what you need.
