You mean, if the server use AFS, which is authenticate via samba/3rd
party kerberso, then samba able to support their ACL completely or still
drop into standard posix rwx kind of permission?

It's the problem, because user will prefer to change the file system
performance from windows client file explorer, and the permission can
vary under each subfolder/files at particular samba share folder, the
simplest way is control everything by POSIX ACL.

My initial ideal is can AFS authenticate via samba 3/4, and the folder
permission under AFS can control by samba? At the same time, can windows
client control delete, modify, and others AFS operation via share
