Different passwords can result in the same MD5 hash. The purpose of the salt is to prevent users from abusing this (i.e. logging in with a different password that happens to hash to the same value). Which means the user should not know what the salt is since that makes the salt pointless. Your notion about what the salt is above (#3) is wrong. Agree with scorpio17 that normally the salt and the encrypted password are stored together. Would be interested in knowing the reason why they are separated.
