Which eDirectory object type is located at the top-most level of the eDirectory tree?

Leaf objects such as User, Printer, and Server reside at the lowest levels of the tree and cannot contain other objects, placing them at the bottom of the hierarchy, not the top.

The Tree root object (shown as [Root] in eDirectory tools) is the single top-most object in any eDirectory tree and serves as the common ancestor for all other objects in the hierarchy. Every container - such as Organization and Organizational Unit objects - and every leaf object exists somewhere below the Tree root. It defines the boundary of the entire eDirectory tree.

Container objects such as Organization and Organizational Unit objects hold other objects but are themselves subordinate to the Tree root, so they do not occupy the top-most level.

Redirector object is not a defined object class in the eDirectory schema and does not exist as a standard eDirectory object type.

The eDirectory schema governs object class and attribute definitions but is not itself an object positioned at the top of the directory tree.

Tree boundary object is not a standard eDirectory object type and has no defined role in representing the top level of the directory hierarchy.
