[Samba] Samba AD domain member with SSSD: ACL not work

[L.P.H. van Belle]

Have you seen : 

( centos/redhat )
https://outsideit.net/realmd-sssd-ad-authentication/ 

( debian/ubuntu ) 
http://www.alandmoore.com/blog/2015/05/06/joining-debian-8-to-active-directory/

but i must say, i havent tested/tried these, i dont use sssd.
But i think these are usefull for you to read at least.

If you use the debian variant, you may need to install also :
One or more of these : libnss-sss libpam-sss libsss-idmap0 libsss-sudo

But same as Rowland is saying, you get better support at the sssd list.
