How does Teradata handle a change in password controls?

If there is a change to the password controls, e.g. PasswordDigits is changed from N to R in SysSecDefaults, when does the rule get enforced for accounts with non-expiring passwords?

If I have a number of user accounts with non-expiring passwords, some of which already adhere to the new rule and some that do not, will Teradata identify which need to be changed to be brought in line and prompt for a change next time the user account attempts to log on or will it let the accounts carry on with the inadequate password indefinitely?
