Our saslauthd does:

  # Status should be 'OK' or error message
  my $Status = $Result ? 'OK' : $Reason;

  $Self->WriteNginxResponse(
    'Auth-Status' => $Status,
    'Auth-Server' => $BEServer,
    'Auth-Port' => $BEPort,
    'Auth-User' => $BEUserName,
    'Auth-Pass' => $BEPassword,
    'Auth-Wait' => $WaitTime,
  );

Why does the auth fail on the backend server?  It never should.  If it does
that means you've screwed up pretty badly.  You can give the failure from
nginx by just passing an Auth-Status header.
