Yup, you are absolutely right, in both GPO management and 'samba-tool 
gpo listall' I get 4 GPOs, but only 3 are listed in 

The one missing there is "*Default Domain Controllers Policy*", aka 

If I rerun samba-tool ntacl sysvolreset, I get the same error:

connect_acl_xattr: setting 'inherit acls = true' 'dos filemode = true' 
and 'force unknown acl user = true' for service sysvol set_nt_acl_conn: 
init_files_struct failed: NT_STATUS_OBJECT_NAME_NOT_FOUND 
ERROR(runtime): uncaught exception - (3221225524, 'The object name is

service=service) File "/usr/lib/python3/dist-packages/samba/ntacls.py", 
line 238, in setntacl service=service, session_info=session_info)

Should I delete this policy from AD? Or maybe recreate the internal 
structure somehow? 'samba-tool gpo create ....'?
