[Samba] sysvolreset doesn't reset all ACLs

Ok, rechecked this, your correct. This did work fine. 

In now at samba 4.6.7, you? 
This worked untill ( last i checked ) 4.6.5  :-(( now sysvolreset is totaly
broken.  :-((
New thing for my ToDo list.. 


Try this script, the rights are my defaults "after a sysvol reset" 
Place the script somewhere within /var/lib/samba
Preffered that location .
Run it with : bash script.sh sysvol/
! Check the group numbers and make sure you match yours. 
Then at least your rights are correct again. 
After this, goto you gpo manager, klik ever gpo, you get a message, klik ok. 

Greetz, 
Louis
