Thank Luis, Thank Rowland.

Yes, I have read this howto, and many others.
None show howro setup correctly ACLs with SSSD.
Nobody talk about ACLs + SSSD.

Then I came to the conclusion that samba + sssd + acls are not working
yet.

.... or use winbind, as I have always done with samba3

Then Yesterday in 5 minutes I installed, configured and activated
winbind and now all work fine.

IMHO: probably it would be useful write in some howto that "samba AD
Member based on sssd have some problem with ACLs (not work yet)", so
that others users like me do not waste time (2 days) attempt to make
them work.

Many thanks to all

Dario
