Re: One bad PIN entry locks card

PROBLEM SOLVED

Thanks, everyone! The problem turned out to be in our use of JSS.

The JSS PK11Token login method takes a password callback handler. The
handler has a getPasswordAgain method that's used for retries, and
returning anything but null will result in a locked card.

The handler should look something like this:

    PasswordCallback pwcb = new PasswordCallback() {
        @Override
        public Password getPasswordFirstAttempt(PasswordCallbackInfo info)
throws GiveUpException {
            return new Password(pin.toCharArray());
        }
        @Override
        public Password getPasswordAgain(PasswordCallbackInfo info) throws
GiveUpException {
            return null;
        }
    };

This results in the expected IncorrectPasswordException when the PIN is bad.

Thanks again -
Ernie
