Installation#

This page contains troubleshooting advice for FreeIPA server installation. For trouble shooting other issues, refer to the index at Troubleshooting.

Server Installation#

When installation crashes, check installation log in /var/log/ipaserver-install.log.

If the installation crashed on installing PKI server (Dogtag), check it’s logs as well. The most useful logs are the following:

  • /var/log/pki/pki-ca-spawn.$TIME_OF_INSTALLATION.log

  • /var/log/pki/pki-tomcat/catalina.out

  • /var/log/pki/pki-tomcat/ca/system

  • /var/log/pki/pki-tomcat/ca/debug

pki-selinux policy not loaded properly#

If you see in ipaserver-install.log line: /usr/bin/runcon: invalid context: unconfined_u:system_r:pki_ca_script_t:s0: Invalid argument" Then the culprit might be that pki-selinux failed to load its policy. The best thing to do is to force re-install pki-selinux (and check for any errors in the /var/log/messages file or journal).

Replica Installation#

When installation crashes, check installation log in /var/log/ipareplica-install.log. When CA is being installed on a replica, check the aforementioned PKI logs as well.

Migrating from RHEL 6/CentOS 6#

  • Installation of certificate server fails with:

    Clone does not have all the required certificates

    It indicates bug 1322059. Issue is that RHEL6, while creating replica file, uses certificates from a file which was created during server installation and potentially contains expired certificates instead of fetching the certs from database where they are valid. It is fixed on FreeIPA 3.2+. Recovery is to update the file with valid certs and then run ipa-replica-prepare again and try replica installation again:

    1. create a /root/dbpass file containing the ‘internal’ (not ‘internaldb’) password from /etc/pki-ca/password

    2. create a /root/dmpass file containing the DM password

    3. run PKCS12Export:

    4. #PKCS12Export -debug -d /var/lib/pki-ca/alias -p /root/dbpass -w /root/dmpass -o /root/cacert.p12

  • Installation of certificate server fails with:

    Error while updating security domain: java.io.IOException: 2

    It indicates bug 1256039. The issue is that certificate server users on master server has invalid, usually expired cert, in its database entry even though all certs tracked by certmonger are valid. Recovery is to update the database entry with correct certificate. Run following script or use manual method is described at freeipa users list mail.

    # /usr/share/pki/scripts/restore-subsystem-user.py -v

Replica Installation fails with Invalid Credentials#

  • Installation of the replica fails with:

  [27/40]: setting up initial replication
Starting replication, please wait until this has completed.
Update in progress, 15 seconds elapsed
`1`` <ldap://master.example.com:389>`__\ `` reports: Update failed! Status: [49  - LDAP error: Invalid credentials]
  [error] RuntimeError: Failed to start replication
Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.
ipa.ipapython.install.cli.install_tool(CompatServerReplicaInstall): ERROR    Failed to start replication
ipa.ipapython.install.cli.install_tool(CompatServerReplicaInstall): ERROR    The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information

This can happen when the ipa-replica-install command is called with –no-ntp and the clocks of the master and the replica are not in sync. Once they are synchronized (either manually or with NTP or chrony), ipa-replica-install should succeed

Client Installation#

When installation does not work as expected, check installation log in /var/log/ipaclient-install.log. You can run installation in verbose mode if you run ipa-client-install with --debug option. (Log files always contain debug information, so you do not need to re-run installation with --debug option.)

Installation breaks on decoding/downloading CA certificate#

  • `ipa-client-install` may crash with error like

    ipalib.errors.LDAPError: failed to decode certificate: (SEC_ERROR_INVALID_ARGS) security library: invalid arguments.

  • This may mean that PKI CA Certificate stored in LDAP was not properly imported during upgrade in some of the older versions

  • Verify that the CA certificate is stored correctly

    $ ldapsearch -h your.ipa.server.fqdn -x -b "cn=CAcert,cn=ipa,cn=etc,dc=example,dc=test"

  • The cACertificate;binary should contain the encoded certificate, typically starting with MII characters

  • If the certificate is missing, go to any FreeIPA master to let updater regenerate it:

    # kinit admin # ldapdelete -Y GSSAPI "cn=CAcert,cn=ipa,cn=etc,dc=example,dc=test" # ipa-ldap-updater --upgrade

Failed to update DNS records#

When client cannot update the DNS record in FreeIPA managed DNS zone:

  • Make sure that the respective FreeIPA DNS zone has Dynamic Updates option enabled:

$ ipa dnszone-mod zone.name.example. --dynamic-update=TRUE

  • Make sure that the FreeIPA server with DNS service has port 53 opened for both UDP and TCP (related user case)

Installation breaks on Joining realm#

ipa-client-install may fail with the following error:

Joining realm failed: Failed to add key to the keytab
child exited with 11

Installation failed. Rolling back changes.

This failure may be caused by an empty /etc/krb5.keytab. In this case, simply delete the file and restart the installation.
