Do Not Show System Messages When Unsuccessful Logon Attempts Occur
Medium Severity

pam_faillock.so
. pam_faillock.so module requires multiple entries in pam files. These entries must be carefully defined to work as expected. In order to avoid errors when manually editing these files, it is recommended to use the appropriate tools, such as

or
authconfig
, depending on the OS version.
