I carried out the same tests on another machine (this time using
'rid'), but this computer did not map Administrator to root with a
user.map
Everything else was the same.
Logged into Win10 as Administrator, I couldn't change anything, I
expected this.
Logged in as myself, I could alter the permissions on the share that
didn't have 'acl_xattr:ignore system acls = yes' set, but on the
other,
I got:
An error occured while applying security information to
\\mintclient\acltest2
Failed to enumerate objects in the container. Access is denied.
When I checked the ACLs with samba-tool, I got these:
sudo samba-tool ntacl get /srv/acl1 --as-sddl
O:S-1-22-1-0G:S-1-5-21-1768301897-3342589593-1064908849-

They are different, this is probably to be expected.
It looks to me that the user.map is required, but you shouldn't set
permissions from Windows as Administrator, you should set them as a
user that is a member of 'Administrators' or 'Domain Admins', or
is a
member of group that is a member of either group.
it also looks like you should set 'acl_xattr:ignore system acls = yes'
on the shares if setting permissions from Windows, but only if you also
set a user.map and never change the permissions as Administrator.
Now to phrase all that in a way suitable for the wiki.
