I'm not sure if I understand correctly Intruder Detection settings.

I have selected Detect Intruders and Lock account after detection. Locking works fine.

I have set Intruder lockout reset interval to 2 Hours. I have understood that the locked account should now unlock automatically after 2 hours from intruder detection. But it does'nt open. When the account is locked, it stays locked until I open it.

What is the meaning of the setting "Intruder lockout reset interval"?
