Set Preferred Active Directory Domain Controllers

Applies to: Hammerspace 5.2 and later.

In a geographically distributed Active Directory environment, authentication is faster when the cluster talks to the domain controllers nearest to it. Naming preferred domain controllers puts them at the front of the list the cluster works through.

This is a preference, not a restriction. The named controllers are tried first; if they cannot be reached, the cluster falls back to the others it knows about.

Set Them While Joining Active Directory

In the GUI, go to Infrastructure  Active Directory. Enter the domain name, login name, password, and organizational unit if you need one. Under AD Servers, select Manual, then add the domain controllers in the order you want them tried, using the + control.
