There's only one conf file in /etc/ipa/, which is default.conf. ca_host
is not defined there. But I think my CA is the IPA server.

Everything is reported running:
# ipactl status
Directory Service: RUNNING
KDC Service: RUNNING
KPASSWD Service: RUNNING
MEMCACHE Service: RUNNING
HTTP Service: RUNNING
CA Service: RUNNING

but when I try # ipactl restart, it reports:
Starting httpd: [Tue Sep 04 08:19:10 2012] [warn] worker
ajp://localhost:9447/ already used by another worker
[Tue Sep 04 08:19:10 2012] [warn] worker ajp://localhost:9447/ already
used by another worker

ajp worker threads are used by tomcat instances of which the CA is one example. It sounds like your CA has gotten into a funny state. I would do a ipactl stop to shut down all your services and then do a ps to look for any Java processes that are still running (I'm assuming the only Java you're running on this box would be for the CA). If you can identify a running Java process that you believe belongs to the CA then kill it and try starting IPA again (or you could use a big hammer and reboot).

BTW, the ajp threads are the listeners on the CA communication ports, if those treads are not in the right state you could see the CA communication problems you reported.

If that still does not work then my next suggestion would be to add this line to /etc/ipa/default.conf

debug=True

and restart IPA, that will cause verbose logging to be written to /var/log/httpd/error_log which may have more detailed messages indicating where things might be going wrong.
