Drat.
So, assuming you have run 'samba-tool ntacl sysvolreset', this is indeed
the issue we have had for a while. I had (incorrectly in your case)
assumed the issue was that IDMAP mappings imported from classic domains
were breaking it. That's why I worked on my patches, which improve the
situation by handling some details at a lower level.
On my fix-acls2 branch, please run 'samba-tool ntacl sysvolreset' then
then, if you don't mind, getting me the level 10 debug log would be very
helpful. Set 'log level = 10' in your smb.conf, then re-run and send me
(personally) the result compressed with xz.
