Hmmm, I can't say I really know however I did see this in the system-auth

auth        required      pam_tally2.so  ideny=3

on mine it states:

auth        required      pam_tally2.so  deny=3

I actually don't have this working however we probably should have...

try this, the order of the pam_tally2.so have to be first above all else, If you google around you should have found this :slight_smile: but if you haven't, there you go

auth required pam_tally2.so deny=3
auth required pam_env.so
auth sufficient pam_fprintd.so
auth sufficient pam_unix.so nullok try_first_pass
#auth requisite pam_succeed_if.so uid >= 500 quiet
auth required pam_deny.so
