TL;DR: Accurately identifying privileged access in Active Directory requires calculating effective permissions across every AD object, because delegated rights, group membership, and ownership changes can all create Domain Admin equivalent control, according to Paramount Defenses. For IAM and PAM teams, the key issue is that privilege assessment must follow actual object-effective access, not directory labels or group names.
Editorial analysis by NHI Mgmt Group, based on content published by Paramount Defenses: “How to Correctly Assess Privileged Access in Active Directory”.
By the numbers:
- At 85% of all organizations worldwide, the vast majority of all powerful privileged access resides in Active Directory.
Key questions
Q: What breaks when Active Directory privilege reviews rely on group membership alone?
A: They miss delegated rights, inherited permissions, ownership changes, and object-level control that can combine into Domain Admin equivalent access.
Q: Why do delegated permissions in Active Directory often count as privileged access?
A: Because delegated rights can include password resets, group changes, GPO linking, or ACL modification on high-value objects.
Q: How can teams tell whether an AD account has Domain Admin equivalent power?
A: They should examine whether the account can modify privileged groups, reset privileged passwords, change object ownership, edit ACLs, manage domain controllers, or alter policies and top-level OUs.
Practitioner guidance
- Map effective permissions on high-value objects Evaluate the AdminSDHolder object, privileged groups, domain root, policy containers, and top-level OUs using effective permissions rather than membership lists alone.
- Treat delegated rights as privileged access Classify password reset, group modification, ACL editing, ownership changes, and GPO linkage as privileged capabilities even when they are granted for administrative convenience.
- Rebuild privilege from object control paths Trace who can modify the permissions, ownership, or membership of privileged objects, then compare that view to your formal privileged account inventory.
Bottom line: Active Directory privilege is not defined by labels alone, because effective permissions can combine delegation, inheritance, ownership, and group control into hidden administrator-equivalent access.

Effective permissions are the true privilege boundary in Active Directory: directory labels, role names, and group membership snapshots are insufficient once delegation and inheritance are in play. AD privilege is determined by the net result of all applicable access paths on the object. For IAM and PAM teams, that means the assessment unit must be the object, not the directory label.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- 42% of machine identities have privileged access and 61% of organisations lack identity security controls for cloud workloads, according to CyberArk's 2025 Identity Security Landscape.
A question worth separating out:
Q: Should organisations recertify Active Directory access by object or by group?
A: By object. Group recertification alone cannot reveal the cumulative access created by nested delegation, inherited ACEs, ownership, and control over security-sensitive objects. Object-level recertification gives IAM and PAM teams a truer picture of who can actually exercise privileged access.
