[Pkg-samba-maint] Bug#840382: samba: After upgrade to 2:4.4.5+dfsg-3 samba crashes

Package: samba
Version: 2:4.4.5+dfsg-3
Severity: normal

Upgraded from samba_2:4.4.3+dfsg-4 to 2:4.4.5+dfsg-3. Now samba just crashes on start.

Notably I also saw this while installing:

Failed to preset unit: Unit file /etc/systemd/system/samba-ad-dc.service is masked.
/usr/bin/deb-systemd-helper: error: systemctl preset failed on samba-ad-dc.service: No such file or directory

system log:
