[Samba] Time synchronization issues in Samba 4

I configured my NTP server in samba 4 according to the article "
https://wiki.samba.org/index.php/Time_Synchronisation" however I verified
that the NTP server does not respond to requests from Windows NTPv3
clients, it only responds to NTPv4.

Following my ntp.conf:

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
driftfile /var/lib/ntp/ntp.drift
# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
# Local clock. Note that is not the "localhost" address!
server version 3
fudge stratum 10
# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example
# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
server a.st1.ntp.br     iburst prefer
server b.st1.ntp.br     iburst prefer
driftfile       /var/lib/ntp/ntp.drift
logfile         /var/log/ntp
ntpsigndsocket  /var/lib/samba/ntp_signd/
# Access control
# Default restriction: Allow clients only to query the time
restrict default kod nomodify notrap nopeer mssntp
# No restrictions for "localhost"
# Enable the time sources to only provide time to this host
restrict a.st1.ntp.br  mask    nomodify notrap nopeer
restrict b.st1.ntp.br   mask    nomodify notrap nopeer

can anybody help me?
