In Active Directory we need to know who has the keys to our organizational units (OUs), the place where our users and computers live. Over the years OUs have grown to meet needs. Different teams may have been delegated access for managing users, groups, and computers. Then you come along as the new administrator. You probably have no idea where permissions have been granted to your OUs. And the scary thing is… neither does anyone else. I know, because I’ve been there. I hear the same thing from our customers.
Out-of-the-box we do not have a specific tool to report all of the OU permissions. You have to click each OU and view the security tab one-by-one, and we all know that is entirely impractical. Today’s post contains a free script download to generate a report of this vital information.
I would advise all Active Directory shops to review this report on a quarterly basis to make sure there are no surprise administrators lurking in your domain.
