unsuccessful login count reset:
If a user's unsuccessful login count reaches a max value (loginretries=<value>), the user is not enabled to login into the system.
1. check unsuccessful login count:
# lsuser -f user01
loginretries=3
pwdwarntime=0
account_locked=false
unsuccessful_login_count=5 <--it is higher than the max value
2. reset the login count:
# chuser unsuccessful_login_count=0 user01 <--it will reset to 0 the number of unsuccessful login count
