Issue

A RHEL IPA replica re-install using the command ipa-replica-install may fail with the error

  [5/29]: configuring certificate server instance
Failed to configure CA instance
See the installation logs and the following files/directories for more information:
  /var/log/pki/pki-tomcat
  [error] RuntimeError: CA configuration failed.
Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.

CA configuration failed.
The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information

And this message does show the underlying error and reason.

This may happen during migration or RHEL IdM upgrade scenarios from, RHEL-7 to RHEL-8
