Nope, it's exactly right. That's how crypt()-based authentication works,
precisely. It needs to know what salt the original password was encrypted
with, so it's the first two characters of the encrypted password. It
crypt()s the attempted password (from the authentication attempt) with the
same salt, and if the two match, the password must be the same
(theoretically).
