This sounds really good too. This will give them a more descriptive error
instead of password error as suggested before. A password error will often
simply mean that and end up confusing the client in most cases. But a
permission denied error could result in them thinking, 'Hey, maybe I should
pay my bill on time next time'. Thanks for the tip.
