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

2 Datacentres
2 IPA servers at each datacentre \_ datacentre A / \_ datacentre B /

The datacentres are linekd, but bandwidth not great.

Client's in datacentre A should therefore use and 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

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.
