Red Hat Summit22.6. Resolving invalid credential errors
If an IdM replica installation fails with an Invalid credentials error, the system clocks on the hosts might be out of sync with each other:
[27/40]: setting up initial replication
Starting replication, please wait until this has completed.
Update in progress, 15 seconds elapsed
[ldap://server.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
If you use the --no-ntp or -N options to attempt the replica installation while clocks are out of sync, the installation fails because services are unable to authenticate with Kerberos.
To resolve this issue, synchronize the clocks on both hosts and retry the installation process.
Prerequisites
-
You must have
rootprivileges to change system time.
Procedure
Synchronize the system clocks manually or with
chronyd.- Synchronizing manually
Display the system time on the server and set the replica’s time to match.
[user@server ~]$ date Thu May 28 21:03:57 EDT 2020 [user@replica ~]$ sudo timedatectl set-time '2020-05-28 21:04:00'Synchronizing with
chronyd:See Using the Chrony to configure and set system time with
chronytools.
- Attempt the IdM replica installation again.
