similar to: Samba Time Synchronisation wikipage

I have update the Time Synchronisation Wikipage: https://wiki.samba.org/index.php/Time_Synchronisation It now includes information for the 'chrony' time server. If you spot any errors or omissions, or if you think that something could be said better, please report back ;-) Could I also thank Louis Van Belle for proofreading the page. Rowland

Hai, https://docs.microsoft.com/en-us/windows-server/networking/windows-time-service/how-the-windows-time-service-works Look in the above link, search for "Time Synchronization in an AD DS Hierarchy". There you find the PDC Emulator role. In the piramide. ;-) This one explains even better then the technet link. It also explains Alexei's question i believe. Greetz, Louis

DC that doesn't holding PDC emulator FSMO role should sync it's time with DC that holdings such role. Right? But I can understand how it works in case of samba DC without PDC emulator FSMO role and with NTP server configured according to https://wiki.samba.org/index.php/Time_Synchronisation#Set_up_the_ntpd.conf_File_on_a_DC . Doesn't it create conflict between samba potential to sync

Hi I'm running samba 4.7.6 on ubuntu 18.04 as (backup / secondary) domain controller that joined to an Existing Active Directory (Windows 2012R2 server). The question is about Time Synchronization across the domain. How should I configure chrony v3.2 in order to provide time synchronization: 1. between main Windows DC and Samba DC 2. Between Samba DC and windows clients in case when

Thank you. May it be better to add to wiki page instruction to use in ntpsigndsocket directive of ntpd / chrony config file the path that received from NTP_SIGND_SOCKET_DIR line of the output of samba -b command ?

It wasn't particularly Chrony related question. The question applies to Samba DC that not holds PDC emulator FSMO role with any NTP server.

The output is: alexei at ubuntu-dc:~$ sudo samba -b | grep 'SIGND' NTP_SIGND_SOCKET_DIR: /var/lib/samba/ntp_signd On Sun, Jun 3, 2018 at 5:32 PM Rowland Penny via samba <samba at lists.samba.org> wrote: > > On Sun, 3 Jun 2018 17:11:47 +0300 > Alexei Rozenvaser <alexei.roz at gmail.com> wrote: > > > On Sun, Jun 3, 2018 at 4:51 PM Rowland Penny via samba

By the way there is ntpsigndsocket option in chrony configuration file. https://chrony.tuxfamily.org/doc/3.3/chrony.conf.html#ntpsigndsocket Can you please look at https://wiki.alpinelinux.org/wiki/Setting_up_a_samba-ad-dc and may be https://chrony.tuxfamily.org/comparison.html ?

Hi All, I am currently running a setup with a main DC ad1, that has ntpd installed and is currently configured to retrieve the time from the UK NTP time pool. I also have a second backup AD DC, ad2, on which I have not installed ntpd but I have installed ntpdate. My current understanding is that the setup I have just described is in-line with the recommended best practices outlined in the

But according to following command output chrony on my samba dc already serves the windows clients: alexei at ubuntu-dc:~$ sudo chronyc clients Hostname NTP Drop Int IntL Last Cmd Drop Int Last =============================================================================== 192.168.0.45 4 0 7 - 501 0 0 - - 192.168.0.72

OK. But according to my best knowledge so far: There is no automatic fall over of Single-Master roles in Windows Active Directory. You can only transfer or seize it. In other words all machines which AD members - always trying to sync their time with current PDC Emulator even if it is offline, unless you transfer or seize this role to other DC manually.
