[Samba] Missing Policies folder in AD and /var/lib/samba/sysvol

[Rick Hollinbeck]

I currently am running 3 Samba DC's.

None of them have a 'Policies' folder under /var/lib/samba/sysvol (only 
'scripts')

My Samba migration started from a Windows Server 2008 configuration 
several years ago.

I first installed Samba 4.11 (van-belle), joined it to the Windows AD and
migrated the FSMO roles there.
I then removed the Windows Servers and turned them off.

This set-up worked fine until a Windows update broke AD logins with 
Samba 4.11 from Windows 11 so...
A year or so ago, I added a Samba 4.17 server and migrated FSMO roles there.

So, I'm not sure when (or if) the Policies folder got lost along the way.

Is there a way to manually repair these Default GPO's?
