Add all different constraint.
This is a very simple all different constraint, e.g. - It does not know that if there are more variables than candidates, it has reached a contradiction. - It does not know that, if there are as many variables as candidates, if only one variable can take on a candidate value, then all other candidates for that variable can be eliminated.
