The mod_dbacl module for ProFTPD uses the mod_sql module for SQL table access; the module uses SQL tables for reading ACLs for files/directories.

For further module documentation, see mod_dbacl.html.

• Integrate into core engine's dir_hide_file() check, so that files can be hidden via mod_dbacl configuration, rather than simply denying the FTP commands which might operate directly on the file (e.g. if mod_dbacl config would deny access to a file, do not list that file in a directory listing of an allowed directory).
