Thanks for all the suggestions guys.
I was already working on an ldapsearch, so in the end I've gone with:
/usr/bin/ldapsearch -h ipaserver.example.com -x -LLL -o nettimeout=2 -b
Reason being that we demand an object is pre-created in IdM/FreeIPA
before the install takes place. We then use localityName to describe
roughly where in our maze of VLAN's the client actually sits. I know I
could search for something more generic to provide a response, but it
seems to make sense to check that the data we expect for a client is
actually in LDAP already.
There's a list of 8 IPA servers to check, so the timeout ensures we
don't waste time waiting around for responses that just aren't going to
Working well for now.

if you know python you can look into the ipa-replica-install tool, as it
does a full check of accessibility. You do not need all those tests (as
you do not need connection back from the server for example). But you
can take inspiration there to see how we test each service.
