lock user account after failed login attempts with FC 10

I am trying to figure out how to lock a user account after 3 failed attempts (incorrect passwords) with FC10. I have tried two methods.

I added the following lines two the default rules list that came with
FC 1- in /etc/pam.d/system-auth-ac


auth required deny=3
account required

If I tail -f /var/log/secure

I see that is pam_tally(su:auth): user xxxx (501) tally 4 deny 3

However once I enter in the right password no matter how high the tally, I still log in successfully



auth required deny=3
account required

With this I actually get a brief message saying my account has been locked. However If I just enter in the correct password I login just fine.


So basically I am looking for a config that is compatible with FC10 and will lock a user out after 3 failed login attempts.

Thanks for any help.

You can set LOGIN_RETRIES in /etc/login.defs. See:

man login.defs
