[Samba] Can't get 'root preexec' to run

[Ole Traupe]

I think I finally managed to understand the [homes] part of the man 
pages, and what my problem is:
https://www.samba.org/samba/docs/man/manpages/smb.conf.5.html

The misunderstanding comes from my practice I learned on Windows to just 
share the "\\server\home" directory and to create per-user sub-folders 
(\\server\home\newuser) that *themselves are not shared*.

If you - as you obviously should (at least referring to Samba) - put 
"\\server\newuser" as home dir path into your user config on the DC, the 
manpages start beginning to make sense: The Samba file server receiving 
the request to connect to \\server\newuser finds no appropriate share 
entry in the smb.conf and, thus, clones the content of the [homes] 
section (given the username exists and the password is correct) for 
creating a new share (actually shared, no simple subfolder of a share).

So the user home must actually be a share and the [homes] section with 
the 'root preexec' parameter has to be defined on the Samba server 
hosting those home shares.

Will try this tomorrow.
