To add a user double click the Add User icon.
        Doing this creates a user with the default name
        user1. Double clicking this user opens the
        user editor docked at the bottom of the application.
      
        In the User Editor, set the user's name using
        the Name text box and set the password
        using the Password text box. Assign one
        role or a number of roles to the user by selecting the desired
        roles from the text area on the right and then clicking the
        < button. Roles may be revoked by
        moving them in the opposite direction.
      
Right clicking a user opens a pop-up menu. These options function as described in Section 7.3.3.1, “Adding Roles”.
