           Summary: FtpWebRequest logs into the wrong user directory on
                    Windows FTP servers
           Product: Mono: Class Libraries
           Version: 2.0.x

        OS/Version: openSUSE 11.0
            Status: NEW

         Component: System

When accessing a ftp account on a Windows server, the FtpWebRequest is logging
into the root directory of the server, instead of the home directory of the

On login, the Microsoft .NET implementation sends a PWD command to obtain the
starting directory, and then sends a CWD command to that same directory (maybe
as a safety measure).

The Mono implementation, doesn't send the PWD command at all, but it does send
a "CWD /" command that changes the current directory to the root of the server.
This is not the appropiate behaviour for connecting to a Windows FTP Server.

This is a sample code where this behaviour can be cheched:

   FtpWebRequest ftp =
   ftp.Credentials = new NetworkCredential("username", "xxxxx");
   ftp.Method = WebRequestMethods.Ftp.PrintWorkingDirectory;
   FtpWebResponse response = (FtpWebResponse)ftp.GetResponse();
   StreamReader sr = new StreamReader(response.GetResponseStream(),
   string result = sr.ReadToEnd();
   Console.WriteLine("Working directory: " + result);
