What this checks and how to fix it

- Supports delegation review for administrative boundaries

Security Recommendation
Section titled “Security Recommendation”Review OU permissions regularly, especially where OUs host privileged users, servers, or administrative delegation models. Unexpectedly large or complex OU ACLs can indicate legacy delegation that should be validated.
How the Test Works
Section titled “How the Test Works”This test retrieves $adState.DaclEntries, filters entries where ObjectClass equals organizationalUnit, and reports the count of OU DACL entries and distinct OU objects represented.
