Hi,
Below you have the steps that I followed to access to the shares with a domain user through FTP:
1. Install the FTP module, disable the option 'Restrict to personal directories' and enable the module.
2. Through FileZilla, create a FTP connection using a 'Passive' transfer mode.
3. Connect to the FTP server, and then, just search for the path '/home/samba/shares'.
I also tested with SFTP, I enabled PAM and then, I could be able to connect to the shares through Filezilla. I think, this method requires steps 1 and 3 from above.
