Of course, if you can create enough users (and passwords), you can try an attack to recover $secret.
That's the thing about hashes and reverse lookups; given a hashed value, the reverse lookup table gives you an input that hashes to that hash value, not necessarily the input that was used initially. So, I think that by employing your scheme, an attacker is highly unlikely to recover the secret. Of course, I'm not a cryptographer, so I may be missing something.

Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
