> The password generator used to generate passwords for identities needs to generate passwords
based on a rule set rather than just a random sequence of characters. 
> In a KDC (MIT or Active Directory), there may be a policy in place requiring a certain
characteristics for the password. By creating a password consisting if 18 characters pulled
randomly from {{abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890?.!$%^*()-_+=~}},
there is no guarantee that any specific policy will be met. 
> The following rules should be settable:
> * Length
> * Minimum number of lowercase letters (a-z)
> * Minimum number of uppercase letters (A-Z)
> * Minimum number of digits (0-9)
> * Minimum number of punctuation characters ({{?.!$%^*()-_+=~}})
