I was thinking that it could be done similarly to the way Ohloh does it, e.g. that there is a "this is me" button visible on author pages for logged in users. When clicked, the author id would be linked with the user. This could potentially be abused, but any misbehaving users could be blocked (I don't really think it will be a problem though). Alternatively, there could be a second step where a link gets emailed to the Author mail address and the user has to click it (will be a hassle for author profiles with invalid email addresses though, e.g. "at" instead of "@").
