6.2.3. Authentication
Please note that the user account covered here are applicative user account handled by the RVT.
Once the TCP/IP, USB or Modbus connection has been established to the server, the client must authenticate itself.

and granting them certain rights to do things.

mand will be accepted before an authentication is performed. The only exception is for the local administrator user
that is automatically detected based on its local connection to the server.
