Is it possible for the sssd clients to round-robin their requests between 2 or more servers? Is this an sssd question or generic enough to be in this list? Would this functionallity be of use to freeIPA in general?

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.
