Description Scott Poore 2016-09-24 01:15:48 UTC
Description of problem:

In some test environments we are seeing ipa-replica-install fail occasionally during ipa-replica-conncheck.

2016-09-24T00:43:55Z DEBUG args=/usr/sbin/ipa-replica-conncheck --master master.testrelm.test --auto-master-check --realm TESTRELM.TEST --hostname replica.testrelm.test --principal admin --password XXXXXXXX --ca-cert-file /etc/ipa/ca.crt

This can happen if they are already bound to an application
and ipa-replica-conncheck cannot attach own UDP responder.

2016-09-24T00:44:00Z DEBUG stderr=Remote master check failed with following error message(s):
ipa-replica-conncheck returned non-zero exit code

Version-Release number of selected component (if applicable):

How reproducible:
unknown but seen multiple times in test environments.  Mostly in OSP test environments but, I believe we may have seen this earlier in testing in local VM type tests as well.  That we thought had gone away after some release.

Steps to Reproduce:
1.  Install IPA master with DNS
2.  Point resolv.conf on replica to IPA master
3.  Set hostname on replica to match domain of master
4.  on master add DNS record for replica (with a-rec and a-create-reverse)
5.  Install replica with DNS and CA in one step process

Exact command failing:
ipa-replica-install -U --setup-dns --forwarder <DNSFORWARDERIP> --setup-ca --ip-address <REPLICAIP> --server master.testrelm.test --domain testrelm.test --admin-password Secret123 --principal admin

Actual results:

Fails during conncheck

Expected results:

Installs cleanly.

Comment 2 Scott Poore 2016-09-24 01:24:05 UTC
Also, note that if I manually run client install and then conncheck, it works.  But, I can uninstall the client and re-run replica-install and it fails.  Some kind of timing issue possibly?
