Using SharePoint object model, setting up our custom web service on SharePoint box and access it.

    1:              SPUser spUser = null;
    2:              string authError = "Could not authenticate user";
    3:              try
    4:              {
    5:                  spUser = web.AllUsers[impUser];

    7:                  {
    8:                      writer.Write(string.Format("spUser = web.AllUsers[impUser]; failed<br/>"));
    9:                      throw new UnauthorizedAccessException(authError);
   10:                  }
