Any Active Directory® object can be a container of other objects. This can clutter the user interface, so it is possible to declare that a objects of a specific class be only be displayed as a leaf in the user interface. The treatAsLeaf attribute is a single-valued display specifier attribute that determines if objects of that class should be only be displayed as leaf objects. This attribute is a Boolean value that, if TRUE, indicates that objects of the class should only be displayed as leaf elements. If FALSE, indicates that objects of the class can be displayed as a container or a leaf. Like all display specifier attributes, the treatAsLeaf attribute is set on a per-locale basis, so this attribute can be localized as needed. For example, the User-Display for the English locale (0409) display specifier has the treatAsLeaf attribute set to TRUE by default. This causes the user interface to display all User objects as leaf objects.
