samba - May 2018 - Samba4 on Ubuntu 18.04 Howto setup ADDC with bind9_DLZ (extra part 4.8.1 samba)

Hai Paul. 

Yep. time sync is a must in ADDC setups and for very server it a must imo. 

You might need to sync a hardware clock also, because if the hardware clock gets
more then 5 min out of sync.
You might end up en some strang problem. 
And do note, NTP Server is only needed on the DC,s members, just point them to
the DC.
Better imo, add CNAME ntp1 to dc1 and ntp2 to dc2 and use the ntp1/2 .domain.tld
names in the configs.
Now, if you want another ntp, just change the cname endpoint. 

sudo dpkg-reconfigure tzdata
If you setup correct, the base install would have handled that and a
dpkg-reconfigure should not be needed.
being picky here, since you wanted to know .. My way to install.   ;-) 

Greetz, 

Louis

Yeah, you'd think so wouldn't you... but the new -live version of Ubuntu
Server doesn't.

Nothing to do with Samba, but who thought a 'live' server iso was a
good idea ????
