Implement different password strenght settings as a followup to Bug 18298 - Enforce password complexity
Maybe we could just have different strength settings? Instead of "RequireStrongPassword" we could name this PasswordStrength and then have the current and alphanumeric+digits as first two options.
Case sensitivity could be an issue, see Bug 16282
There already is an implementation for this feature.
