After a decent amount of online searches, I am a little bit lost on
the subject of Samba4 in AD mode and ACL's. Could anybody help with
the following please:

1. Is it correct that my default ACL's are being ignored (new files
created don't follow the default ACL's permissions of the parent
folder) because "inherit permissions = " is set to No by default in
smb.conf?

2. Is "inherit permissions = " still a valid option in smb.conf for
Samba4 in AD mode, or has it been deprecated?

3. Does "inherit permissions = " have the same effect as clicking
"Enable inheritance" button on the Windows side in the share settings?




If you are using an AD DC as a fileserver, you do not add anything to
the share other than the path and read only mode, you need to set the
ACLs from windows, see here:

Thank you for that. Where I got confused is that many howtos seem to suggest that ACL's can be managed either from the Windows side, or with setfacl on the Linux side.

I noticed that if I have the following ACL's

# file: VAT
# owner: root
# group: MYDOM\134domain\040users
user::rwx
group::rwx
mask::rwx
other::---
default:user::rwx
default:group::rwx
default:mask::rwx
default:other::---

The inheritance doesn't work correctly, in spite of the default ACL's. It seems that it only works correctly if there is an explicit default ACL for "Domain Users" - in spite of the fact that the "Domain Users" is the owning group, and there is a default ACL for the owning group. Is this by design?
