In a roundabout way it is documented in 'man smb.conf'. There is is also 
the 'root preexec' parameter and in 'man smb.conf' it says this:

This is the same as the preexec parameter except that the command is run 
as root.

Which implies that the 'preexec' is run as a normal user.

Of course patches to improve the documentation are always welcome 😁
