Well, you can tell your boss that there's no way since UNIX passwords aren't encrypted, but hashed, which is a one-way operation. So unless, as Jim said, there's a paper trail or someone else kept a list already you're out of luck. Of course, if the users were allowed to change their passwords themselves and did so, even that is good for nothing.
