Check Text (C-238201r958452_chk)

Verify that "use_mappers" is set to "pwent" in "/etc/pam_pkcs11/pam_pkcs11.conf" file: $ grep use_mappers /etc/pam_pkcs11/pam_pkcs11.conf use_mappers = pwent If "use_mappers" is not found or the list does not contain "pwent" this is a finding.

Fix Text (F-41370r653777_fix)

Set "use_mappers=pwent" in "/etc/pam_pkcs11/pam_pkcs11.conf" or, if there is already a comma-separated list of mappers, add it to the list, separated by comma, and before the null mapper. If the system is missing an "/etc/pam_pkcs11/" directory and an "/etc/pam_pkcs11/pam_pkcs11.conf", find an example to copy into place and modify accordingly at "/usr/share/doc/libpam-pkcs11/examples/pam_pkcs11.conf.example.gz".
