The LocalUser property determines if the server should 
          perform user authentication using the Windows local account database. 
          If this option is not specified, the application is responsible for 
          creating virtual users using the AddUser method or implementing 
          an OnAuthenticate event handler and authenticating client 
          sessions individually.
          If this property is set to True, a client can authenticate 
          as a local user, however the session will not inherit that user's 
          access rights. All files that are accessed 
          or created by the server will continue to use the permissions of the 
          process that started the server. For example, consider a server 
          application that was started by local user A. Next, a 
          client connects to the server and authenticates itself as local user B. When that client uploads a file to the 
          server, the file that is created will be owned by user A,
          not user B. This ensures that the server application 
          retains ownership and control of the files that have been created or 
          modified.
          The default value for this property is False.
