[Samba] systemd unit to start Samba as AD DC

[mathias dufresne]

Hi all,

Here is my [seem-to-be] working systemd unit to deal with Samba 4.

I'm using Samba 4.3.1 compiled mainly with no option except for
diredctories where I used --enable-fhs (and  --prefix=/usr
--sysconfdir=/etc --localstatedir=/var).

samba-ad.service file content
------------------------------------------------------------------------------------
[Unit]
Description=Samba Active Directory Services
Documentation=man:samba(8)
After=network.target

[Service]
Type=forking
PIDFile=/var/run/samba/samba.pid
LimitNOFILE=16384
EnvironmentFile=-/etc/default/samba
ExecStartPre=-/usr/bin/mkdir /var/run/samba
ExecStart=/usr/sbin/samba -D  -M standard
ExecReload=/usr/bin/kill -HUP $MAINPID
#FailureAction=

[Install]
WantedBy=multi-user.target
------------------------------------------------------------------------------------

I start from https://dev.tranquil.it/wiki/SAMBA_-_Fichier_systemd_samba4

As the few options used during ./configure made my Samba pid file store in
/var/run/samba I had to force this directory creation at start time using
ExecStartPre.
I kept #FailureAction hoping I figure out what kind of action I could place
there.

For it works I had to place that file in [/usr]/lib/systemd/system then to
enable it via systemctl:
systemctl enable samba-ad.service

Just placing that file in /etc/systemd/system/multi-user.target.wants/ gave
me possibility to launch samba through systemctl but samba was not started
at boot time.

Perhaps that would help someone, perhaps it would be only noise :)

Kindly regards,
