Windows Security Log Event ID 4662

4662: An operation was performed on an object

• Description of this event
• Field level details
• Examples

Active Directory logs this event when a user accesses an AD object. 

Of course the object's audit policy must be enabled for the permissions requested and the user requesting it or a group to which that user belongs.

For tracking property level changes to AD objects I recommend using Directory Service Change events (5136...) instead of this event because 5136, etc provide much better information. 

On the other hand this is the only event that reports accesses defined for auditing that do not qualify as property changes. 

For instance changing the permissions on an OU such as for delegating administrative authority requires the WRITE_DAC permission which would get logged by this event.

Of course I don't recommend auditing read only accesses on AD objects since the value is questionable and would typically generate many, many events.  So on the whole I regard this event as noise and recommend disabling the "Directory Service Access" subcategory in your audit policy on domain controllers.
