I am not sure what is going on here, but I did notice that you had
'acl_xattr:ignore system acls = yes' set on 'test', but commented out,
was it ever set and used ?
if you break the ACEs down, you will find that Domain Admins is
'S-1-5-21-185628584-2620904409-2800336372-512' in one and just 'DA' in
the other and I have no real idea why.
I have done some testing in the past and found that how
'acl_xattr:ignore system acls = yes' works depends on if there is a
user.map set and just who changes the permissions on Windows,
Administrator or a member of Domain Admins.

It might just be easier to create a new share.

You should be able to do all that from Windows.

I am not sure setting that line is a good idea, just set the permissions
from Windows and never change them on the Unix side.
