Red Hat Summit34장. Uninstalling the IdM CA service from an IdM server
If you have more than four Identity Management (IdM) replicas with the CA role in your topology and you run into performance problems due to redundant certificate replication, remove redundant CA service instances from IdM replicas. To do this, you must first decommission the affected IdM replicas completely, then reinstall IdM on them without the CA service.
While you can add the CA role to an IdM replica, IdM does not provide a method to remove only the CA role from an IdM replica: the ipa-ca-install command does not have an --uninstall option. This limitation applies to all other IdM server roles, including DNS server, KRA server, AD trust agent, and AD trust controller. In each case, removing a role requires fully decommissioning the replica and reinstalling it without the unwanted role.
Prerequisites
- You have the IdM CA service installed on more than four IdM servers in your topology.
Procedure
- Identify the redundant CA service and follow the procedure in Uninstalling an IdM server on the IdM replica that hosts this service.
- On the same host, follow the procedure in Installing an IdM server: With integrated DNS, without a CA.
