#4291 CA not start during ipa server install in pure IPv6 env
Closed: Fixed None Opened 5 years ago by mkosek.

Ticket was cloned from Red Hat Bugzilla (product Red Hat Enterprise Linux 7): Bug 1081561

Description of problem:
ipa server install ended with "CA did not start in 300s" in pure IPv6 env

Version-Release number of selected component (if applicable):
ipa-server-3.3.3-27.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1.In /etc/hosts
Remove : 127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
Add         : <ipv6> <hostname> <shortname> (IP FQDN shortname)
2.delete ipv4 address
3.stop ip6tables
4.ipa-server-install

Actual results:
install is not finished with
'CA did not start in 300s'

Expected results:
install is successfull

Explicitly specify the prefix length (127.0.0.1/32) to avoid this warning.
This special behaviour is likely to disappear in further releases,
fix your scripts!

If master is getting disconnected after deleting ipv4 addr,
try to ssh -6 with ipv6 addr from replica:

Hacky workaround is to modify /usr/share/ipa/ipa-pki-proxy.conf to use 127.0.0.1 instead of localhost as confirmed by dgilmore in #freeipa. That will at least complete the install and ipa cert-show 1 works. Whether everything else works is unknown.

During processing of remaining tickets in 4.2 Backlog, this ticket was found as suitable to be fixed in the nearest bugfixing branch - which is 4.2.x.

FreeIPA 4.2.1 was released, moving to 4.2.x.

Adjusting, according to recent fix in pki.

According to https://bugzilla.redhat.com/show_bug.cgi?id=1082663#c10 the only thing to add is to add

[Tomcat]
pki_ajp_host=::1

so probably (not sure) in cainstance.py:

config.add_section("Tomcat")
config.set("Tomcat", "pki_ajp_host", "::1")
