[Samba] Disable password complexity does not work?

[Szymon Życiński]

Hello

I use Samba 4.0.9 and want to disable strong passwords. I've run:
./samba-tool domain passwordsettings set --complexity=off

But it seems to not work. If users try to change password via 
ctrl+alt+del windows still require strong password. Restarting samba to 
commit change did not solve problem.

Is there something i forgot? On my old configuration with old (RIP) 
server it worked flawessly.
