23장. Generating CRL on the IdM CA server


If your IdM deployment uses an embedded certificate authority (CA), you may need to move the generating of the Certificate Revocation List (CRL) from one Identity Management (IdM) server to another. It can be necessary, for example, when you want to migrate the server to another system.

Only configure one server to generate the CRL. The IdM server that performs the CRL publisher role is usually the same server that performs the CA renewal server role, but this is not mandatory. Before you decommission the CRL publisher server, select and configure another server to perform the CRL publisher server role.

23.1. Stopping CRL generation on an IdM server

To stop generating the Certificate Revocation List (CRL) on the IdM CRL publisher server, use the ipa-crlgen-manage command. Before you disable the generation, verify that the server really generates CRL. You can then disable it.

Prerequisites

  • You must be logged in as root.

Procedure

  1. Check if your server is generating the CRL:

    [root@server ~]# ipa-crlgen-manage status
    CRL generation: enabled
    Last CRL update: 2019-10-31 12:00:00
    Last CRL Number: 6
    The ipa-crlgen-manage command was successful
  2. Stop generating the CRL on the server:

    [root@server ~]# ipa-crlgen-manage disable
    Stopping pki-tomcatd
    Editing /var/lib/pki/pki-tomcat/conf/ca/CS.cfg
    Starting pki-tomcatd
    Editing /etc/httpd/conf.d/ipa-pki-proxy.conf
    Restarting httpd
    CRL generation disabled on the local host. Please make sure to configure CRL generation on another master with ipa-crlgen-manage enable.
    The ipa-crlgen-manage command was successful
  3. Check if the server stopped generating CRL:

    [root@server ~]# ipa-crlgen-manage status

    The server stopped generating the CRL. The next step is to enable CRL generation on the IdM replica.
