12.3. Adding a certificate mapping rule in the IdM CLI for users whose AD entry contains the whole certificate


  1. Obtain the administrator’s credentials:

    # kinit admin
  2. Enter the mapping rule and the matching rule the mapping rule is based on. To have the whole certificate that is presented for authentication compared to what is available in AD, only allowing certificates issued by the AD-ROOT-CA of the AD.EXAMPLE.COM domain to authenticate:

    # ipa certmaprule-add simpleADrule --matchrule '<ISSUER>CN=AD-ROOT-CA,DC=ad,DC=example,DC=com' --maprule '(userCertificate;binary={cert!bin})' --domain ad.example.com
    -------------------------------------------------------
    Added Certificate Identity Mapping Rule "simpleADrule"
    -------------------------------------------------------
      Rule name: simpleADrule
      Mapping rule: (userCertificate;binary={cert!bin})
      Matching rule: <ISSUER>CN=AD-ROOT-CA,DC=ad,DC=example,DC=com
      Domain name: ad.example.com
      Enabled: TRUE
    注意

    If mapping using the full certificate, if you renew the certificate, you must ensure that you add the new certificate to the AD user object.

  3. The System Security Services Daemon (SSSD) periodically re-reads the certificate mapping rules. To force the newly-created rule to be loaded immediately, restart SSSD:

    # systemctl restart sssd
