I have got to fix it first and I found another bug:

rowland at devstation:~$ samba-tool -V
samba-tool: no such subcommand: -V

4.14.8-Debian

It really shouldn't print 'samba-tool: no such subcommand: -V', it is
an option not a command.

'-k yes' and '--use-kerberos=required' need to be replaced with a
variable, so the correct one is used, base on the samba-tool version.
