Hello Takashi,

sorry for the delay.  I don't manage the server in question, so I can't 
call 'smbstatus' directly on it, but if it's any indication of version 
there is a path :

/usr/share/doc/samba-4.10.16/

Also, attached is the /etc/smb.conf file, somewhat redacted.

Thanks for looking at this.
Philippe
