samba - Dec 2018 - How to change the server info/version which Samba returns to the client?

Dear Samba team,

I would like to change the server info string which Samba returns to the 
client.
I tried to change the "server string" setting in /etc/samba/smb.conf:

[global]
    server string = Master

# testparm | grep "server string"
         server string = Master

# /etc/init.d/samba restart

but the server still returns the string "Samba 4.2.14-Debian":

$ smbclient //localhost/home -U guest%guest -c ls
Domain=[WORKGROUP] OS=[Windows 6.1] Server=[Samba 4.2.14-Debian]
   .                                   D        0  Mon Dec 17 00:01:54 
2018
   ..                                  D        0  Mon Jan 29 20:20:52 
2018

It looks like "server string" setting has no effect or I am changing
the
wrong
setting.

Additional info:

# dpkg -l | grep samba
ii  samba    2:4.2.14+dfsg-0+deb8u11   i386   SMB/CIFS file, print, and 
login server for Unix

That's because you are mixing up 'Server' and 'server
string'
The 'Server' is the Samba version and 'server string' is
something to
identify the computer, see 'man smb.conf' for more details.

Also, Samba 4.2.x is EOL, you should, if possible, upgrade.

Thanks for this hint. I've tried to locate any other
"server"-related
option in man smb.conf, but I failed. Could you please tell the exact
option which I should use?

Many thanks in advance!
