[chrony-users] Configuring chrony on SAMBA4 AD server

[Varga Péter]

Hello

Our company uses a SAMBA4 server for Active Directory authentication for
Windows 10 hosts. Unfortunately, we're struggling with time
synchronization, the hosts are unable to synchronize the time properly.
We've found this page
<http://blog.mycroes.nl/2013/03/setting-up-ntp-signing-ntpsignd-with.html>,
and our guess is that we need to insert these  two lines into the
/etc/chrony.conf:

/ntpsigndsocket /usr/local/samba/var/lib/ntp_signd restrict default mssntp/

But the chrony service stopped working completely after that.

Our other question is that according to this site
<https://wiki.samba.org/index.php/Time_Synchronisation> at the
requirements topic, do we need ntpd enabled with signed ntp support?
What is this exactly? Is this essential for us to make chrony working?

Thanks in advance,

Peter Varga

I forgot to mention that our SAMBA4 server is running on Ubuntu 16.04
and the chrony version is 2.1.1.

Hi,

I forgot to mention that our SAMBA4 server is running on Ubuntu 16.04
and the chrony version is 2.1.1.

That feature has been added in chrony 3.0.

Cheers,

Hi,

Since then we have also figured it out, and changed for ntpd.
Thanks anyway :)
