If this is not the case, the following command can be run to fix: # /usr/sbin/authconfig --passalgo=sha512 --update This ensures that when users change their passwords, hashes for the new passwords will be generated using the SHA-512 algorithm.`,`Test incorrectly performing check as all referenced files have correct changes and still fails`
`set_system_login_banner`,`To configure the system login banner: Edit /etc/issue. Replace the default text with a message compliant with the local site policy or a legal disclaimer.
