[Samba] Managing samba ad dc with systemd

[Igor Sousa]

Hi,

I have a question about samba 4 with systemd. I've followed the "Managing
the Samba AD DC Service Using Systemd" and I've created
/etc/systemd/system/samba-ad-dc.service file with the following content:

[Unit]
Description=Samba Active Directory Domain Controller
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
ExecStart=/usr/local/samba/sbin/samba -D
PIDFile=/usr/local/samba/var/run/samba.pid
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target


I've created a mask to smbd, nmbd and winbind and I've disabled them
following this command: # systemctl mask smbd nmbd winbind # systemctl
disable smbd nmbd winbind. But, when I've use systemctl stop samba-ad-dc to
stop samba, the status shown is "failed" with code=exited and status=127.

Is it normal behavior?

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