Found the problem, after digging some more through the documentation:

    [ in Controller, which known $user ]

    $field->validator('Callback')->callback( sub {
        return Crypt::SaltedHash->validate($user->password, shift);
    });

One more question, how do I set a custom message? I use

    - type: Password
      name: password_old
      label: Old password
      validator:
        - type: Callback
          message: Password does not match

together with above line, but that does not really help (works for
constraints, though). Still just says 'Validator error'.
