 The core CIFS protocol does not provide unix ownership information or mode for files and directories\&. Because of this, files and directories will generally appear to be owned by whatever values the uid= or gid= options are set, and will have permissions set to the default file_mode and dir_mode for the mount\&. Attempting to change these values via chmod/chown will return success but have no effect\&.
