how to change rule and text of password error in CreateUserWizard?

[Dan]

Hi,

I want to set up the password length to 5 and no non-alphanumeric
chararcters required, and obviously change the error text in the
CreateUserWizard in case of wrong password, instead of the standard rule
(Password length minimum: 7. Non-alphanumeric characters required: 1). Is
that possible? I know the security is then lower, but it's all a matter of
relationship between security and easyness.

Thanks for help
Dan
