FTP login from Active Directory


I would like to do a setup that the people can connect by ftp to upload a website with their credential from active directory. I’m not sure if it is possible, I was able to bind my ubuntu 13 to AD with the likewise client, but for the rest, I don’t know how to andle it? DO you have any idea?

I would wan’t quota by user too, but the first point is more important than this second one.
