pam_tally2 =faillock on RHEL8

Sometimes we have a problem with blocking users. Do you remember on pam_tally2? Let's try command faillock

Linux use PAM policy for authentication. Some users are blocked and you can see via command pam_tally2.

On RHEL 8 (and of course Centos8) is command faillock. 

[root@localhost ~]# cat /etc/redhat-release

[root@localhost ~]#

[root@localhost ~]# faillock

[root@localhost ~]#

to check 

 faillock --user pondelok

to reset user

faillock --user pondelok --reset 

or

# to reset all users
