It is recommended to define several user roles
because also an application firmware may use these
user definitions to behave different in potentially
provided user interfaces depending on the user
who is currently logged in.
A BNA device allows up to 5 user definitions with
different access rights. The root user already
occupies one of these five definitions. Thus, four
additional users or, more accurately, user roles can
be defined.
A user definition consists of three elements. These
are a username or role name, a group membership
and finally a password.
Usernames and password are freely definable. Both
have a maximum length of 8 character. Whereas the
group definitions are predefined, each has specific
characteristics.
Table 6-2 gives an overview of the available user
groups and their properties.
