DELETE PERMISSIONS ON ISILON SMB SHARE

Hello ISILON Community Members:

Is there any way to avoid that files can be deleted in an isilon share by the same user that created that files ? ...  Please, excuse me if can be a silly question. But, our customer is asking if a share with files, they can read, write, but don't allow delete the files .. could that be possible ? .. if yes .. how ? ..

Thank you
