Attempts to authenticate the passed
Authentication object, returning a fully populated
Authentication object (including granted authorities) if successful.
AuthenticationManager must honour the following contract concerning exceptions:
DisabledException must be thrown if an account is disabled and the
AuthenticationManager can test for this state.
LockedException must be thrown if an account is locked and the
AuthenticationManager can test for account locking.
BadCredentialsException must be thrown if incorrect credentials are presented. Whilst the
above exceptions are optional, an
AuthenticationManager must always test credentials.
Exceptions should be tested for and if applicable thrown in the order expressed above (i.e. if an
account is disabled or locked, the authentication request is immediately rejected and the credentials testing
process is not performed). This prevents credentials being tested against disabled or locked accounts.
