OK. This request is tracked here:
Issue 74 – ACL support

Because its SFTPv3 it is not supported over SFTP.
ProFTPD has an ACL and SFTP6 module. Maybe it will work together.

But anyway it should be possible over a seperate SSH Session to manipulate ACL entries.

For ProFTPD see:
SFTPv6 http://www.proftpd.org/docs/contrib/mod_sftp.html sftpProtocolVersion

The mod_sftp module supports SFTP protocol versions 1-6; using any other protocol versions will result in bad configuration.

FACL http://www.proftpd.org/docs/modules/mod_facl.html

I mean if your SFTP server supports it.

Yes it does. You can type getfacl/setfacl in bash.
Protocols are all supported over SSH / Port 22.
But not the FTP/Port 21 ones..
OS: CentOS 6

What protocol? What server do you use? Does your server even support it?

Please add support to set ACL for files/directories and recursive.

The setfacl and getfacl command-line is terrible.
