[Samba] Managing samba ad dc with systemd

Fri Apr 26 14:02:10 UTC 2019

Hi Louis,

I've modify my /etc/systemd/system/samba-ad-dc file following your advice,
I only changed bind9.service to named.service (I've run samba on CentOS 7
with Bind9_DLZ). I've checked again if there are others smbd, nmbd,
winbindd an samba services on systemd, but they there aren't. The
samba-ad-dc service still to fail when I've tried stop it. I've installed
samba 4.10.2 from source on a fresh host that never see any
samba/smbd/nmbd/winbind packages.

[root at king ~]# systemctl list-unit-files samba*
UNIT FILE           STATE
samba-ad-dc.service enabled

1 unit files listed.
[root at king ~]# systemctl list-unit-files winbind*
UNIT FILE       STATE
winbind.service masked

1 unit files listed.
[root at king ~]# systemctl list-unit-files smbd*
UNIT FILE    STATE
smbd.service masked

1 unit files listed.
[root at king ~]# systemctl list-unit-files nmbd*
UNIT FILE    STATE
nmbd.service masked

1 unit files listed.

[root at king ~]# systemctl stop samba-ad-dc
[root at king ~]# systemctl status samba-ad-dc
