I see you're having a valid point about the outage support. This could be 
worked around using the
"High Availability Add-on" in RHEL, sharing an IP address between your IPA 
servers, which you
would switch to the currently active IPA server.

With regards to IPA's host-based access control: What about doing access 
control through using
netgroups via the tcp wrappers?

You could still be configuring host based access control in IPA as it's 
creating transparent
netgroups for the host groups.

These are all workarounds, I assume having the functionality available trough 
the native sssd
would be of an advantage. But this way you would the mentioned extra 
functionality of SSSD without
having to do the work of supporting your competitors operating systems. :)
