HP-UX Directory Server 8.1 administrator guide

3. There are three tabs that display the schema elements loaded in Directory Server: Object
Class, Attributes, and Matching Rules.
The Attributes tab is broken into two sections for default and custom attributes. Both sections
show the attribute name, OID, syntax, and whether the attribute is multi-valued.
The Object Classes tab shows the list of object classes on the left. When an object class is
highlighted, its OID and superior object class are listed in the fields at the top and its required
and allowed attributes are listed in the boxes on the right.
