It will not be there, samba-tool doesn't have the code to create the 
users folder, but when created on Windows, Windows does.

The problem is, to get it to work correctly, you need to ensure that you 
do not change the users homeDirectory attribute (this is what 
'--home-directory' sets). Also a 'root preexec' script is obviously run 
as 'root', so of course any directories will be created with root 
ownership. This means the script needs to change ownership etc.

I have a script that will give you pointers, it isn't really tested, but 
you are welcome to a copy.
