HaCluster and Active Directory prerequisites

Prerequisites for Active Directory connection

Back to HaCluster

Clock is important.

Ensure the time between your Artica servers are the same with your Active Directory server(s).
We suggest using your Active Directory server as a Time Server (see Enable NTP service on Windows 2019 above in order to synchronize time between your Artica servers and your Active Directory).

Domains and DNS

Ensure Artica server hostnames use the same DNS of your Active Directory.
Ensure Artica servers use your Active Directory (or you dedicated DNS connected to AD) as first DNS servers used.
