A small group of us have been trying to get our Ubuntu servers fully
integrated into AD with sssd and Samba. We have slowly chipped away at
the issues. We believe we are left with one major issue: Windows cannot
set ACLs through Samba. The Windows permission dialog seems to work, but
when you click Apply they vanish, and getfacl on Ubuntu shows they were
The host is Ubuntu 16.04.2, up to date as of today, so sssd
1.13.4-1ubuntu1.1 and Samba 2:4.3.11+dfsg-0ubuntu0.16.04.3.
Our AD is set up with OU.AD3.UCDAVIS.EDU
as a child domain in the same
forest as the parent domain, AD3.UCDAVIS.EDU
, with users in
and computers and groups in OU.AD3.UCDAVIS.EDU
The sssd part seems to be setup correctly. We can login via SSH and auth
correctly with Samba. Windows honors the ACLs that are set on the Ubuntu
side, but setting ACLs on Windows fails to actually apply. The Samba
config is attached.
[storage] is on ZFS with:
root@phys-adtest:~# zfs get all storage | grep acl
storage aclinherit restricted local
storage acltype posixacl local
And [storage2] is on ext4 with the user_xattr mount option added.
The behavior, where ACLs vanish after clicking Apply in Windows is the
same with both of them.
I had previously found a thread with the issue on a Samba mailing list
indicating it "must be a sssd issue because it works with winbind", but
can't find the thread now.
Anyone have any clues as to what may be going wrong or what config
options I should check? I can post debug logs if it would help.
