This sounds to me like you are failing to consider the effects of the
order of entries in pg_hba.conf --- ie, in the first case the connection
is being caught by a TRUST-mode entry (or at least, not a password-based
one ... could be IDENT as well). Don't forget to SIGHUP the postmaster
after editing pg_hba.conf, too.
