> # Object Classes Tab of Schema Configuration

> Use this tab to view information about all object classes that currently exist in your directory schema. Select one of the object classes in standard object classes or user-defined object classes lists to view its required and allowed attributes. You may also create, edit or delete user-defined object classes using this tab. You cannot edit or delete the standard object classes that are provided with the directory.

> Schema checking. The status line above this tab indicates whether schema checking is enabled or disabled. When schema checking is enabled, only entries conforming to the object classes and attribute syntaxes defined on the schema tabs may be created in the entire directory. By default, schema checking is enabled.

> Use the button in the upper right to disable or enable schema checking.

> Standard Object Classes (Read-Only). This list includes all standard object classes provided with the directory. Select one of the object classes to view its properties in the other fields. The standard object classes include configuration objects used by Directory Server and other Sun ONE products. You cannot edit or delete the standard object classes.

> User-Defined Object Classes. This list includes all customized object classes currently defined in the schema. Select one of the object classes to view its properties or to edit or delete.

> Required Attributes. This list shows the required attributes for the currently selected object class. The required attributes include those that are inherited. When you add an entry of this object class to the directory, you must provide a value for all required attributes.

> Allowed Attributes. This list shows the optional attributes for the currently selected object class. The allowed attributes include those that are inherited. When you add an entry of this object class to the directory, you may define values for any of the allowed attributes.

> Parent. This field identifies the object class from which the currently selected object class inherits attributes and structure.

> OID. This field shows the object identifier (OID) for the currently selected object class. An OID is a classification string that uniquely identifies an object class or an attribute type definition within a directory and when sharing data between directories. The standard format is a set of dot-separated integers, for example, 2.16.840.1.113730.3.2.2.

> Create. Click this button to display the dialog box for creating a new user-defined object class.

> Edit. Click this button to edit the selected user-defined object class.

> Delete. Click this button to delete the selected user-defined object class.
