It is the safest approach, but you should familiorize yourself with Systemd! :) > > On 12/2/18 11:49 PM, john doe wrote: >> Correction, 'ad-dc' is controled by the 'samba-ad-dc.service' and not >> by the nmbd.service. > > Ok. > > > But what do the error messages mean? > You can use samba in two ways: - Active directory domain controller (1) - Samba daemons and related services (smbd,nmbd,winbind) (2) You either use one or the other. Debian provides both possibilities that is why 'samba-ad-dc' is also included but masked (see (3) for what "mask"ed means). If you have a "small domain" and want to use the DC as a file server you will still need winbind (not recommended by the samba team) (1). > 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 director > The perl script 'deb-systemd-helper' (4) is responsible for the error because the 'samba-ad-dc.service' is masked, but as far as I can tell, everything is working properly though. > > Should I file a bug report against the samba package? > What I would do is to get in touch with the script "author"/maintainer(4) to confirm whether it is a bug or if the error message could be improved. 1) https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller 2) https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Standalone_Server 3) https://www.freedesktop.org/software/systemd/man/systemctl.html 4) https://manpages.debian.org/stretch/init-system-helpers/deb-systemd-helper.1p.en.html Note that this e-mail is folded by my mailer. -- John Doe
