well, I'm guessing that guy is hosted at dreamhost, as he's asking for local server paths, not real urls. Dreamhost changed the way users can be added to databases - they must now all be unique.
Besides that, why would you give out your password to someone you probably don't know - you have no way of knowing what happens with your details and passowrd after you click submit. Besides, his statement of "(for verification, you know.)" seems rather fishy to me. I'd sigguest you look arund and find a conversion process you can carry out on your own.
