How can I create a Custom Password Filter?

[luusid]

We would like to create a custom password filter that isn't as strict as the default password filter.


The default password filter (passfilt.dll) included with Windows 2000 requires that a password:

Does not contain all or part of the user's account name
Is at least six characters in length
Contains characters from three of the following four categories:
English upper case characters (A..Z)
English lower case characters (a..z)
Base 10 digits (0..9)
Nonalphanumeric (For example, !,$#,%)



We would like to restrict it to 8 characters minimum with either lower or upper case characters (a..z) and at least one base 10 digit (0..9)

So pretty much just (2 of 3) instead of (3 of 4).

Any ideas on how to do this?



Thanks,

David
