For the benefit, or added confusion, of future generations, some
observations
ipa-ca-install, run successful replica instantiation w/o --setup-ca
fails consistently with the errors in my orig post. Never figured out
what the script was finding that needed purging. After a multitude of
attempts (thank you, ESXi snapshots) with multiple ipa-server-install
--uninstall's , i gave up and rebuilt from the gound up withlatest
packages and --setup-ca which works great
I found that installing a replica with firewalld enabled would
consistently fail during initial replication. Disabling firewalld
always allowed replication and later stages to complete
[24/38]: setting up initial replication
Starting replication, please wait until this has completed.
[ipa.localdomain.local] reports: Update failed! Status: [-1 - LDAP
error: Can't contact LDAP server]
The first master and all replicas are all CentOS Linux release 7.2.1511
(Core) with ipa-server-4.2.0-15.0.1.el7
One other thing. if, during ipa-replica-install,+ you choose the
default answer to the following:
Existing BIND configuration detected, overwrite? [no]:
ipa.ipapython.install.cli.install_tool(Replica): ERROR Aborting
installation.
Not sure if that is intended? Which BIND configuration is being detected?
Anyhow, up and running with 4 replicas, 2 of which will be split off to
a failover instance of ESXi in the future. When it works, it's a joy
Now back to getting these Mac clients to play nicely with IPA ...
thanks for the help and advice

Is what i'm seeing normal? Would this 2-node setup in this state
survive failure of the master?
It will until the certificates start expiring. You want at least 2
CA's to avoid a single point of failure situation.

It detects whether a CA is installed by the existence of something
like /var/lib/pki-tomcat/ca. You can use pkidestroy to remove any
remnants that might be left over from some previous failed install.
Or it could be that something wasn't updated properly in LDAP and
there actually is a working CA. You might try manually starting the CA
to see if it comes up, and/or run ipa-csreplica-manage to see if there
are any working agreements.

Hi
Somehow i picked the wrong cookbook when i provisioned my first (and
only) replica and it lacks CA aso, as pointed out in a recent thread,
creates a single point of failure. Not ready to set up more 2
replicas
yet and am still in testing. Is it possible to replicate the master's
CA to the replica without destroying and reprovisioning with
--setup-ca
this time?
Use ipa-ca-install on the replica.
Simo.
