Active Directory - List and Set/Fix AD users not inheriting permissions

updated: 2013/03/29

Inherited permissions are those that are propagated to an object from a parent object. Inherited permissions ease the task of managing permissions and ensure consistency of permissions among all objects within a given container.

If the Allow and Deny permission check boxes in the various parts of the access control user interface are shaded when you view the permissions of an object, the object has inherited permissions from a parent object. You can set these inherited permissions by using the Permissions tab of the Advanced Security Settings properties page.
