CentOS - May 2016 - access denied from windows changing security setting when i use a folder connected to a fake drive made with dd

i make a image file connected to /dev/loop0 formated as ext4 partition
and connect it
losetup /dev/loop0 /root/disk.img

then make format the loop drive with
mkfs.ext4 -o rw,usrquota,grpquota /dev/loop0 /disk
connected it to /test

the only way to write there other users except root is setting with
chmod o+w /test

from windows 7 using samba 4 i can write to folder but i cannot set
security setting getting always access denied when i am setting
security settings on the share

what is wrong

thank you

Yes, that is expected.

You haven't told us anything about your Samba configuration, so it's 
impossible to say.

I'll make a wild guess though.  You're using "security = user"
and
possibly mapping users to a guest account.  IIRC, you can only change 
items in the Windows security tab if you're using "security =
domain" or
"security = ads"

i will tell you about my setup

my setup is done with the command samba-tool domain provision --use-rfc2307
--interactive on the version 4.3.9 that i am thinking for me that version
is enough stable the last version doesn't have any more the
"Authenticated
Users"

it is active directory my server setup i am suspicious that is something
wrong when i am connecting to a loop device that is made this way dd
if=/dev/zero of=imgfile bs=1M count=60 for example
then losetup /dev/loop0 imgfile and formating it as ext4 filesystem

but only root have there write access am i doing something wrong?

this path is connected to a smb.conf with the following way:

[test]
        path = /path (where is mounted the loop device)
        read only = no


thank you
