Auto-unlock does not generate an event, because no change happens to the
account. When the account is locked, the DC sets a lockouttime timestamp on
the account to say when it is allowed to log back on. When someone uses the
account, the DC checks the timestamp- if it is 0 or in the past, the account
may be used. If it is in the future, the DC returns the error that the
account is locked.
