You can temporarily lock out accounts when users attempt to log on using an incorrect password. You can set the specified number of times within a specific period of time that a log on attempt can be made before the account is locked out. You can also set the lockout time.
When you set Enabled failed log in lockout, you can set the rules for how to handle an account if a password is invalid. User accounts are locked out according to the rules you specify in the following fields.
Number of consecutive failed logins allowed. This is the number of attempts allowed before the account is locked out. The default is 10. When this is set to 0, the account is not locked out no matter how many times invalid passwords are entered.
When this number is exceeded, the account status is changed to lockout.
Time to lockout the account. This is time in either days, hours, minutes, or seconds that the account is locked out after the user fails to log in. The account status is automatically changed to active after this time expires. When this is set to 0, the user is locked out until the correct password is entered or the administrator resets the password.
Time window in which the failed logins must occur within to lock the account. This sets the time within which invalid passwords must be entered to trigger the lockout. When this is set to 0, users can log in only with the correct password or if the administrator changes the status from locked out to active.
The rules can be set up by COS or for individual accounts.
Go to Configure>Class of Service or Manage>Accounts.

When this is checked, set the number of consecutive failed logins allowed. The default is 10.
