samba - Sep 2016 - Windows7/Samba3 password cannot be changed after win. update

Hi all,

I followed the recomandations from here:
https://lists.samba.org/archive/samba/2016-August/202208.html.
I have uninstalled the KB3167679 update but this doesn't work.

Do you have any other workaround? I like my samba 3 DC and don't want to
switch to samba 4 immediately.

Thanks for your help,
 -Alexis
