If true, allows remote access to the desktop via the RFB
protocol. Users on remote machines may then connect to the

Hi,
Please check document in #2. Looks like login is a must of setting password.

Once you are connected to the VNC server, execute the following command to
display the VNC server's graphical configuration tool, and then configure a
password for the VNC connection:
