As a privileged user, I need to see how many times the user unsuccessfully attempted to log on. Run this command to see the number of attempts:

/usr/sbin/lsuser -a unsuccessful_login_count <username>

Note: replace <username> for the user account in question.

Run the following command to reset the failed attempt count back to zero:

/usr/bin/chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s <username>
