}}}


PS1:
  Individual users can provide both user and view-only passwords. These should be different. Users can give the view-only password to someone so that they can see the remote session, but not interact.TurboVNC assigns access based on which password is used. The user password lets you provide mouse and keyboard input. [[BR]]

PS2:
  I set 2 passwords for both user & view-only,and passwords are different for all-level users. [[BR]]
