I am trying to wrote a password validation module that instead of just going GOOD/BAD, allows tracking of number of logins and attempts to prevent beople from hammering, brute force cracking, and other cracking methods.

What I am asking is less of a how do I pass the type of bad login back to the calling script?

1. Have it return a list first element being 1 or 0 for sucessful or uncucessful and second element being the type of error?

2. Have it return the truth value and set $! to the error type. ( I tried this and in the calling script when I tried to print $! it seems that it was not passed back )

3. Have one element with the type of error or "good login" if sucessful.

What do you all think is the best way to do this?
