Before you turn on user authorization, ensure that at least one user has administrator rights. If you are unsure, check this in the User dialog: Access rights.
  1. Using Manager, select Settings > User authorization.
  2. In the User authorization dialog, choose which modules require user authorization.
    Note define usersdefine users, in the User selection settings. (More information.)
