Users are added from either the Authority or Organization perspective, depending on the security class of the person adding the new user. If added by a user that has the 'Authority Security' feature enabled, the 'Organization' dropdown listbox will be displayed. If the user only has the 'Organization Security', the new user will be automatically assigned to the same organization as the initiating user.
The assignment of security class for the new user is governed by the security class of the initiating user; no user may grant to another a security class that is higher than their own.
