samba - Jun 2017 - Problems with time synchronism on Samba 4 DC

Hi,

The Windows and Linux workstations are not synchronizing the time with the
Samba 4 DC. I have verified that the problem is permission.

I'm using Samba 4.6.3 on Debian 8.

In this way the stations are with different schedules from the DC.

Do I need to configure any GPOs?

What is the maximum time the computer clock can differ from DC ?

Regards,

Márcio

What do you mean with "different schedules form the DC"?

You can find the answers to these questions in any AD documentation
about time sync. It's not something Samba-specific.

However, we have the answer to this question also in our docs:
https://wiki.samba.org/index.php/Time_Synchronisation

I didn't have Policy issues on my Windows workstations, perhaps because they
were domain
members before, but I did have the issues described in this link:

https://www.meinbergglobal.com/english/info/ntp-w32time.htm

"Some w32time versions are unable to query time from NTP servers ...  NTP
servers may not
respond to the type of queries sent by w32time ..."

The link describes the issue, and the solution I use on my AD's Windows
workstations (also
described in the link) is, Windows command line:

w32tm /config /manualpeerlist:mail,0x8 /syncfromflags:MANUAL 
w32tm /config /update

--Mark
