We recently implemented a system wide password policy that uses a
challenge response for users to reset their own forgotten passwords.

Question is, what can be done if a person forgets what they put for
answers to their challenge response questions?

I know, I know, I can't believe it's happened either, but I've had two
people forget so far.......................sigh

Is there any way I can reset a user to have to recreate their challenge
response stuff, or anything along those lines?
