samba - Jul 2019 - SAMBA AD DC - Windows explorer.exe crashes on security tab access

I have a Raspberry Pi 3 B+ with Raspbian Buster and a Samba AD DC is running on
it. Everything works fine, I use Active Directory Users And Computers and
Computer Management on Windows to control the users and the Samba share
permissions. Until this point everything works fine, but the following error
raised on Windows.

If there is a shared directory which was made by mkdir command and a UNIX user
is the owner and/or a UNIX group is the group owner the following happens in
Windows.

I do right click on the shared directory, select Properties and on the property
window I select the Security tab the explorer.exe crashes and the property
window being closed.
This phenomenon does not occur if the directory is made on Windows.

I found a mailing thread about this problem on samba mailing list:

https://lists.samba.org/archive/samba/2018-August/217676.html

But the thread ends with no solution unfortunately. The suspect that this is a
bug related to Windows OS. Maybe someone who has met this error (bug?) and could
help?

The samba version is 4.9.5-Debian. The OS on client machines is Windows 10
(1903). This error occurs on all Windows machines. I tried it on Windows 7
machine as well, the situation is the same.

Thank you!

Best,

Abraham

Ah, that thread, this is a Windows bug and if I remember correctly, they 
were supposed to be looking into it.

Jeremy, did we ever here anything about this ?

I experienced a Windows Explorer crash in

Try samba-tool ntacl sysvolreset (or check first).

I got sidetracked with other stuff, and didn't
bug the Microsoft engineers with it whilst I
was up in Redmond recently, sorry.

Can you write up a method of reproducing
and I'll see if someone at Microsoft can
get the client team to take a look ?

Thanks,

Jeremy.
