Goal

How to configure Hyperion Shared Services to work with an MSAD primary and secondary domain controller so that if the primary fails, the secondary controller will authenticate users. The aim here is to have transparency in case of a failure of the primary domain controller. 

Solution

There are many solutions available but the easiest two to implement are:

1. Setup a DNS alias that resolves to the IP addresses of the Primary and secondary domain controllers and configure Hyperion Shared Services (HSS) to use the DNS alias.

2. Setup two MSAD providers in Shared Services as separate external providers putting the primary as being first in the search order.
