Closed: Invalid None Opened 11 years ago by dpal.

Description of problem:
install ipa server, uninstall, then reinstall fails intermittently with error:
Configuring named:
  [1/9]: adding DNS container
  [2/9]: setting up our zone
  [3/9]: setting up reverse zone
  [4/9]: setting up our own record
  [5/9]: setting up kerberos principal
  [6/9]: setting up named.conf
  [7/9]: restarting named
  [8/9]: configuring named to start on boot
  [9/9]: changing resolv.conf to point to ourselves
done configuring named.

Global DNS configuration in LDAP server is empty
You can use 'dnsconfig-mod' command to set global DNS options that
would override settings in local named.conf files

Restarting the web server
Configuration of client side components failed!
ipa-client-install returned: Command '/usr/sbin/ipa-client-install --on-master
--unattended --domain testrelm.com --server qe-blade-13.testrelm.com --realm
TESTRELM.COM --hostname qe-blade-13.testrelm.com' returned non-zero exit status
1


Can workaround by renaming /etc/pki/nss/cert8.db, and key3.db, and can
reinstall


Version-Release number of selected component (if applicable):
ipa-server-2.2.0-16.el6.x86_64

How reproducible:
intermittently

Steps to Reproduce:
1. install ipa server
2. uninstall
3. reinstall

Actual results:
fails with error:
ipa-client-install returned: Command '/usr/sbin/ipa-client-install --on-master
--unattended --domain testrelm.com --server qe-blade-13.testrelm.com --realm
TESTRELM.COM --hostname qe-blade-13.testrelm.com' returned non-zero exit status
1

Expected results:
be able to reinstall successfully

Additional info:

After reinstalling, it failed, and ipaserver_install.log has -
Domain testrelm.com is already configured in existing SSSD config, creating a
new one.
The old /etc/sssd/sssd.conf is backed up and will be restored during uninstall.
Configured /etc/sssd/sssd.conf
Installation failed. Rolling back changes.

And ipaclient_install.log has error -

May be a slightly different issue, but I can see what seem a possible similar IPA clients install failure, for example with:

Linux ca1.example.com 2.6.18-308.11.1.el5 #1 SMP Fri Jun 15 15:41:53 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
sssd-1.5.1-49.el5_8.1.x86_64 Mon 11 Jun 2012 11:56:14 PM PDT
package ipa-server is not installed

  • successfully registered this IPA client into an IPA domain for example.com
  • uninstall
  • try to register the same IPA client into a different IPA domain, or for "test convenience", in a same IPA domain string, but hosted on different IPA servers, so nearly in a different domain

The IPA client NSS db has been clean up in /etc/pki/nssdb/, but that IPA client file /etc/ipa/ca.crt stays with the older or first IPA enrollment, the CA cert shows the first CA's key id, not the newer one, and the client install fails on trusted cert, although the correct remote DNS servers are up and resolve correctly:

Failed to verify that ipaserver1.example.com is an IPA Server.
This may mean that the remote server is not up or is not reachable
due to network or firewall settings.
Installation failed. Force set so not rolling back changes.
[root@ca1 ~]#

Renaming that older ca cert file /etc/ipa/ca.crt to something else allowed me to re-enroll my test IPA client to a different set of IPA servers successfully.

Is it related to #2702?
Putting into NEEDS TRIAGE.

We can't do much about it. Deferring.

The ticket can be closed. Uninstall and install have been working for a while. FreeIPA no longer uses /etc/pki/nssdb
