Issue

I apllied ACLs on some directories that I'm sharing via Samba to Windows users access it but the ACL permissions are not being honored. In the example bellow I'm seting rwx permissions for /my_dir directory but when I mount this directory as a samba mount on Windows client machine I can not write on that directory:

# setfacl -dm u::rwx /my_dir

# getfacl /my_dir
# file: .
# owner: teach1
# group: teacher
user::rwx
group::r-x
other::---
default:user::rwx
default:group::r-x
default:other::---

# mount / -o remount,acl

On the Windows client side I can browse and access the share using my domain user. However I can not write in the share even with the ACL rwx. How can I fix that?
