I tried on a fresh installation over the Zend Skeleton Application, and the problem is reproducible. When the password field has a leading and/or trailing space, registration always fails. (This is also reproducible in the change password form) It seems that the `Identical` validator on the `passwordConfirm` field is running before the `StringFilter` is run on the `password` field Leading and/or trailing spaces in the `passwordConfirm` are trimed before running the validator, thus making registration always fail. Examples: 1. This does not work password: `123456` confirmPassword: `123456` 2. This does not work password: `123456` confirmPassword: `123456` 3. This works (even though the confirm password has a trailing space, and the password field doesn't) password: `123456` confirmPassword: `123456`
