You could drop the default realm completely, and create a second passdb lookup which uses only the username part to lookup credentials. This means that, as long as you have no conflicts as usernames 'j...@foo.com' vs 'j...@bar.com', you'd be able to support username 'john'. When you're able to use the password in your sql WHERE statement [1] too, you could even work around that, because you'd only have mismatches when 'j...@foo.com' and 'j...@bar.com' have the same passphrase.
