[Samba] rsat permission denied woes

[niya]

hi

i have two domain controllers and a domain member setup to serve home 
directories,

the file system on the server is btrfs and the home directory is a 
subvolume,

i have rsat installed on a windows 10 pro laptop with which i use to 
administer  my domain as administrator,

following the web page 
https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs

i get to Setting ACLs on a Folder,

when i select the security tab i get - you must have read permission to 
view the properties of this object.

i tried the advance button which indicated that it was unable to display 
current owner,

when selecting the permission tab it responded - you do not have 
permission to view or edit this objects permission setting,

i changed the current owner to administrator when i pressed apply it 
responded - unable to select  new owner on directory access is denied.
how do i sort out the permission problem ?

$ ls -al /smb

$ ls -al /smb/home

sudo net rpc rights list privileges SeDiskOperatorPrivilege -U 
"MYDOM\administrator"
Enter MYDOM\administrator's password:
SeDiskOperatorPrivilege:

   BUILTIN\Administrators

$  getfacl /smb/home
getfacl: Removing leading '/' from absolute path names
# file: smb/home
# owner: root
# group: domain\040admins
user::rwx
group::rwx
other::---

$ sudo getfattr -d /smb/home
$

(nothing returned from getfattr)

domain\admin has full control/change and read ,

domain/user have change and read on share permission
