10.7. Adding a New Attribute


You want to add a new attribute to the schema.

  2. In the left pane, right-click on the Attributes folder and select Create Attribute.

  3. Click the Continue button to confirm that you want to extend the schema.

  4. Enter the information for the new attribute.

  5. Click OK.

Using a command-line interface
