You can set the "dfree command" per share, but for use with the home
shares it would need some more configuration.

Yes, this is the problem, you should use "homes".

I think the "get quota command" option is what you are looking for.
It's a global option that specifies a custom script which receives
amongst others information about the directory (e.g. /home) and a
specific user/group. In this script you can use system tools to
determine the needed values (e.g. free/used space). Please refer to the
smb.conf man page for more information about the get quota command.
Probably you'll find such a script for you system by searching for "get
quota command" and your quota system.
