[Freeipa-users] Replica install fails when using --setup-ca

[dbischof at hrz.uni-kassel.de]

Hi,

I have two small FreeIPA installations (for two different realms), both 
with CentOS 6/FreeIPA 3.0.0-42. After running them both with only one 
master server each for a while, I attempted to extend both installations 
with one replica each.

Doing a

ipa-replica-install --setup-ca /var/lib/ipa/replica-info-...

worked fine for one of the installations, but failed for the other:

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.

Omitting "--setup-ca" lets me successfully install a working replica 
server.

The problem appears to be my installation (since the other one works) - 
however: Both (intended) replica servers are nearly identical (operating 
system version, installed packages, etc.).

My understanding is that a replica without a CA is not a 100%-clone of a 
IPA master, right? What are the downsides of having a replica without a 
CA?

Thank you for looking into this,
