If your account is locked out you will see this message:
The lockout is a security control. It locks an account after enough incorrect password attempts, but will automatically unlock after a time period (set by your administrator).
If your account is locked you will need to wait until the lockout time has passed*, then login taking extra care entering your user name and password.
Or if you have forgotten your password, wait until the account has unlocked then click the "Forgot your Password?" link to have an email delivered to you.
*There is not a notification to inform you when the lock time has expired.
You know how to address a locked account.
