Sharing user not for share

Mac OS X 10.5 is driving me crazy! I’m trying to open an FTP access to my machine for sharing some files with a friend. Obviously I turn to the newly renovated file sharing tab, activate it and open FTP sharing. A new feature of Leopard is a new “Sharing Only” user profile that lets you create users for file sharing that will not be able to login to your machine. So I create one of those and give him access to my share folder.

Now that should be the end of it, 15 seconds to share a folder cleanly and securely with someone else. But no…

Thanks to some crazy security freak somewhere in Cupertino, if you try to FTP to my machine with this Sharing Only user, it won’t share, just give you a stupid error that “this user may not use FTP”. It makes absolutely no sense.
