Maybe it is because MemberOf is a constructed attribute? I don't think you can actually set the value of it. When you add a user to a group, the "MemberOf" attribute on that user doesn't get changed directly, only the "Member" attribute on the group you
added them to gets updated. Then when anyone queries the MemberOf attribute for that user it will look for any groups where the user is listed in the Member attribute and will return a list of those groups.
So basically you need to monitor the Member attribute on groups instead if you want to detect when a user was added to a new group.
