Rob Winch c076f0f2e1 SEC-2056: DaoAuthenticationProvider performs isPasswordValid when user not found
Previously authenticating a user could take significantly longer than
determining that a user does not exist. This was due to the fact that only
users that were found would use the password encoder and comparing a
password can take a significant amount of time. The difference in the
time required could allow a side channel attack that reveals if a user
exists.

The code has been updated to do comparison against a dummy password
even when the the user was not found.
