Getfacl/home/TMP/fstab check file permissions, user for themselves, group is subordinate to the group, the other for other users,
To meet the requirements of your apple users and banaba, something like this:
# owner: qwe
# group: JWTS
User: : rw -
Group: : rw -
Other: : -- -- --
Command: chown qwe: JWTS/home/TMP/fstab
Chmod 660/home/TMP/fstab
