non cluster IdP behind hardware load balancer

[Jean Robertson]

Hello,

We are looking for a non-cluster pair of IdP's behind a hardware load 
balancer.

The only reason we want it behind a load balancer is a fast recuperation in 
case of failure.

We are not looking to share load between servers.

We are planning to have a single IdP server run for long periods of time and 
should it fail, the standby would take over.

We know that single sign on is lost in this case.

We are using shibboleth IdP 2.1.5 software

My question:
- how to configure this?

Do we call the AnonymousRelyingParty and DefaultRelyingParty the same in each 
IdP's relying-party.xml config file? (The name being the one that the front 
end is called)

Do we copy the SHIBHOME/credentials cert and key from one machine to the 
other?

Is there something I missed apart from these steps?

I did look for documentation but did not quite find what is being proposed 
here.

Thanks,
