Subject: [Freeipa-users] Specifying load balancing to SSSD clients 

Folks, 

Hopefully this isn't a dumb question, but I'm constrained by a few 
things on my estate and would be looking to deploy something like the 
following: 

2 Datacentres 
2 IPA servers at each datacentre 

ipa1.domain.com \_ datacentre A 
ipa2.domain.com / 

ipa3.domain.com \_ datacentre B 
ipa4.domain.com / 

The datacentres are linekd, but bandwidth not great. 

Client's in datacentre A should therefore use ipa1.domain.com and 
ipa2.domain.com as primary servers and only fail over to ipa3 & ipa4 
when both 1 & 2 are out of action. Clients would revert to using 
ipa1/ipa2 whenever either of them came back online. 

I understand this configuration has already been done as part of 
https://fedorahosted.org/freeipa/ticket/2282 

What I'm wondering is if I can force my clients to load balance 
communication between ipa1 & ipa2. 

I don't have the ability to use the _srv_ records in DNS as that's set 
up for the AD servers on our network. I also can't create separate DNS 
servers for the Linux estate (not that I'd particularly want to). 

Is there any current configuration that I can use to force load 
balancing between ipa1/ipa2 under ideal conditions. Falling back to 
ipa2 when ipa1 is out of action. Falling back to (load balanced 
perhaps?) ipa3/ipa4 when ipa1 & ipa2 are both out of action. 

Hope the description is reasonable. 

Thanks
