Authorization

Four user categories have been predefined for the LHMI and the WHMI, each with
different rights and default passwords.
The default passwords in the protection relay delivered from the factory can be
changed with Administrator user rights.
User authorization is disabled by default for LHMI but WHMI always
uses authorization.
