26.7. Configuring OCSP Responders

Every CA integrated with the IdM server uses an internal online certificate status protocol (OCSP) responder. The IdM service allowing to access the OCSP responders is available at http://ca-server.example.com/ca/ocsp. Clients can connect to this URL to check the validity of a certificate.


For details on OCSP, see the Red Hat Certificate System documentation. For example, 2.2.4. Revoking Certificates and Checking Status in the Planning, Installation, and Deployment Guide.

26.7.1. Changing the CRL Update Interval

The CRL file is automatically generated by the IdM CA every four hours by default. To change this interval:
  1. Stop the CA server.
    # systemctl stop pki-tomcatd@pki-tomcat.service
  2. Open the /var/lib/pki/pki-tomcat/conf/ca/CS.cfg file, and change the ca.crl.MasterCRL.autoUpdateInterval value to the new interval setting. For example, to generate the CRL every 60 minutes:
  3. Start the CA server.
    # systemctl start pki-tomcatd@pki-tomcat.service
