3. Select one or more user accounts from the list in the Security tab. To select more than one row, use the SHIFT key to select a range of users, or use the CTRL key while selecting individual rows.
4. Click Drop user in the Security tab. A dialog appears in which you must confirm the deletion before it is committed.
5. Click OK. The user account no longer appears in the Security tab.
Note: You can view a list of users whose accounts have been deleted (and who, therefore, do not have any active privileges) by selecting the Show Inactive Privileges check box.
