Solution WARNING: The "syslog" option is deprecated

I noticed once a warning in the /var/log/samba/log. file:

[2018/04/13 20:51:05.280655,  1] ../lib/param/loadparm.c:1629(lpcfg_do_global_parameter)
  WARNING: The "syslog" option is deprecated

As reported, the “syslog” option is obsolete, and to prevent the warning from appearing, it must be removed from the configuration.

I opened the configuration file in a text editor:

sudo nano /etc/samba/smb.conf

Found this option:

syslog = 0

And commented on it:

#syslog = 0

After the changes you need to restart samba, you can do this:

sudo service samba restart
sudo restart smbd
sudo restart nmbd

After that, the warning no longer appeared.
