What support does the ASA provide for the ftp auth command? Is it possible to write an access list to permit some users to bypass ftps encryption while others are forced to use encryption? I would like my server to enforce ftp with ssl/tls. However, there are two old legacy scanners that would not be able to use certificates. Can the firewall be of any use in determining who must use ftps? I don't see anything in the ASA documentation to think there would be any assistance, but I thought I would ask anyway.
