That's good - but bear in mind sssd will be set with that IPA server
explicitly so no load balancing or failover with that set up (ie it'll have
an explicit server name and not _SRV_ for discovery)...

I'd strongly recommend making sure go through the list of TXT and SRV
records required to automatically discover the servers... they should be in
the documentation but if it's still playing up I'll grab an example from my
systems.
