add options.strategyName to allow multiple passport-local instances to work in one node.js app;

example code:

passport.use(new LocalStrategy({ strategyName: 'local' }, ... );
app.post('/login', passport.authenticate('local', { successReturnToOrRedirect: '/', failureRedirect: '/login' }));

passport.use(new LocalStrategy({ strategyName: 'local-two' }, ... );
app.post('/another/login', passport.authenticate('local-two', { successReturnToOrRedirect: '/another', failureRedirect: '/another/login' }));
