During ipa-replica-install, http installation first creates a service principal for http/hostname (locally on the soon-to-be-replica), then waits for this entry to be replicated on the master picked for the install. In a later step, the installer requests a certificate for HTTPd. The local certmonger first tries the master defined in xmlrpc_uri (which is pointing to the soon-to-be-replica), but fails because the service is not up yet. Then certmonger tries to find a master by using the DNS and looking for a ldap service. This step can pick a different master, where the principal entry has not always be replicated yet. As the certificate request adds the principal if it does not exist, we can end by re-creating the principal and have a replication conflict. The replication conflict later causes kerberos issues, preventing from installing a new replica. The proposed fix forces xmlrpc_uri to point to the same master as the one picked for the installation, in order to make sure that the master already contains the principal entry. https://pagure.io/freeipa/issue/7041 Reviewed-By: Rob Crittenden <rcritten@redhat.com>
