I'd have to see your current PAM config to tell. Also you need to
examine the failures before you login successfully with that user -
because the account required pam_faillock.so will reset the failures
once the user successfully authenticates.
 
In my file below, I changed the sssd line back to sufficient instead of the stuff I had placed in it before.  When I do a failed login for my sssd account, it does not any longer increment the counter for me (Yay!).

However, in my testing, I'm trying to login as root but the counter is not incrementing.  I've tried both using ssh as well as using the consoles.  Each time I just type a bunch of wrong letters for my root user password, but my counters don't change.  In fact I don't even see the root counter any more.  I wonder if I've broken the faillock mechanism...?
