Lockout policies define how many failed logon attempts users can make before the system locks their accounts. Lockout policies apply to the total number of logon attempts a user makes, regardless of the authentication method used for each attempt.
When you edit a lockout policy, you can change information such as the lockout policy name and the number of failed logon attempts users are allowed to have before they are locked out.
In the Security Console, click Authentication > Policies > Lockout Policies > Manage Existing.
Click the policy that you want to edit, and select Edit.
Make any necessary changes to the lockout policy.
If you have not saved your changes, you can click Reset to restore the password policy to its original state.
