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

[dbischof at hrz.uni-kassel.de]

Hi,

for the record: The problem was a misconfigured Apache on the IPA master, 
cf.

https://www.redhat.com/archives/freeipa-users/2015-February/msg00041.html

In my case, my Apache didn't load proxy_ajp_module and after this was 
fixed, ipa-replica-install --setup-ca worked as expected.

Thanks to Endi Sukma Dewata and Martin Kosek for putting me on the right 
track.
