Hi,
Or at the very least create a script that will be able to take the encrypted password and store it in cleartext as another attribute.
Waste of time. You should use social engineering (hint: password policies)
Not to mention it may be difficult to acheive if all the passwords are strong enough and well encrypted.
If you absolutely need access to the cleartext passwords, the easiest way is to ask your users (with a way to force them to provide it to you: for example the next time they login, you force them to change their password and this time you store it in cleartext).
