	comment = pubstro
	path = /mnt
	create mask = 0777
	force create mode = 0777

--------------------------------------------------------------------
in /mnt directory i have mounted disks

bash# ls -al /mnt
total 24
drwxr-xr-x  4 root root 4096 Oct 11 23:56 .
drwxr-xr-x 24 root root 4096 Oct 11 15:26 ..
drwxrwxrwx  6 root root 4096 Oct 11 23:58 200GB
drwxrwxrwx  8 root root 4096 Oct 12 09:19 250GB

when i try to connect from a windows pc to pubstro
i can't see the contents of /mnt. (directories 200GB 250GB).
