Unfortunately the two things are not completely independent from each other
because the users for / should also have access to /path, just like the unix
"root" user has full access to all files, beginning at / and a user joe
usually only has full access to all files starting at /home/joe

I also read in the documentation of apache that <Location> isnt intended to
restrict access with Auth... commands, we should use <Directory> directives
instead. So I think I have no choice but configuring <Directory> sections for
all underlying physical subtrees of the filesystem which can be accesses
through the URL /path....
