I recently joined joined a new company and while exploring their
Active Directory forest, I came accross strange situation:

If ordinary user opens Active Directory Users and Computers, he can
add and erase users and groups. Moreover, he can add himself to Domain
Admins group as well.

So, I created a test user and sure enough, this test user could use
ADUC to do whatever he wants there. I thoroughly checked GPO's that
applied to the user, and found nothing that would give him such
rights. I checked group memebership for this user and again, he was
not a member of any group with elevated rights. I checked security
rights to user objects via advanced features of ADUC and my test user
doesn't have anything but "read" to them, yet he can kill pretty much
any other account.

While I am thinking that AD itself may be corrupt. I would appreciate
any suggestion, especially if anyone knows of any tool that I can use
to check "effective rights" of any user to Active Directory objects. I
thought it could be a delegation thing, but then I would be able to
see it via "security" tab for any user in ADUC, right?

Thank you, your help is much appreciated
