I also had issues provisioning (well classicupgrade actually) Samba44. I
got segfaults from samba-tool. I did a little bit of debugging, but due to
work time pressures I couldn't submit a bug report at the time. From memory
I think the python code in samba-tool was crashing when accessing code from
security.so, but that might be wrong.
To provision/upgrade the domain I had to install samba43 which worked first
time, however I had to specify --use-ntvfs to classicupgrade. I am unsure
if this has caused any issues, but as domain controllers they seem to work
ZFS only supports nfsv4 ACLs. It seems that Samba can use these just fine,
(see the zfs/acl stuff in my smb.conf from earlier), but samba-tool doesn't
like them. Once provisioned they work really well. I can set them from
FreeBSD using setfacl or from Windows just fine.
I was unable to work on this yesterday as the system is in production,
however I am able to take it offline today to try and figure out what is
