Information
AlmaLinux OS 9 must map the authenticated identity to the user or group account for PKI-based authentication.
GROUP ID: V-269411
RULE ID: SV-269411r1050294
Without mapping the certificate used to authenticate to the user account, the ability to determine the identity of the individual user or group will not be available for forensic analysis.
Solution
Configure AlmaLinux OS 9 to map the authenticated identity to the user or group account by adding or modifying the certmap section of the "/etc/sssd/sssd.conf" file or a "*.conf" file within the "/etc/sssd/conf.d/" directory, based on the following example:
[certmap/testing.test/rule_name]
matchrule = .*EDIPI@mil
maprule = (userCertificate;binary={cert!bin})
domains = testing.test
The "sssd" service must be restarted for the changes to take effect. To restart the "sssd" service, run the following command:
$ systemctl restart sssd.service
