      Negotiate password hashes with MSIE clients using NTLM SSP
      Parameters:
      req - The servlet request
      resp - The servlet response
      skipAuthentication - If true the negotiation is only done if it is initiated by the client (MSIE post requests after successful NTLM SSP authentication).

      Returns:
      True if the negotiation is complete, otherwise false
      Throws:
      IOException - if an I/O error occurs
      jakarta.servlet.ServletException - if a servlet error occurs
