5.1 Users and Roles

Following roles and permissions are defined:

Only the admin role is enabled and the roles super, operator and guest are disabled by default. A user may enable those roles by setting options auth.super.enabled, auth.operator.enabled and auth.guest.enabled. For each role a user account with the respective name is present in the version 2.50.

The authentication subsystem is enabled by default. A user may disable the authentication by the option auth.enabled. The admin has an empty password by default and a user should always set the password after the first login.

A user must provide authentication credentials (name and password) before connecting to the target device from RexDraw, RexView or RexHMI Designer or when using the integrated web interface. An error is returned and the connection is closed if invalid credentials are submitted.
