[keycloak-user] Is there an Event I can trap in KeyCloak when an account status is changed?(ie: temporary locks)

Hi, I'm using KeyCloak 3.4.3.FINAL and looking to see if there is any way I can capture when an account is temporarily locked/unlocked. I was hoping to write an EventListener that would trigger based on an event type, but I can't seem to find anything that fires when then account is locked or unlocked. Is there such an Event in Keycloak? If not, is there a way I can add my own custom events? I'd be okay with trapping an AccountModified event and work with that, but the only event I see fired is the LOGIN_ERROR which doesn't tell me if the account is being temporarily disabled. Furthermore, I can't see any events being fired when the account is re-enabled. Thanks, Eric
