You can do it by having 2 different LocalStrategies to authenticate user and admin differently (in your case from different tables).
Something like :
passport.use('user', new LocalStrategy( //'user' strategy
function(username, password, done) {
User.findOne(/* ... */)
}
));
passport.use('admin', new LocalStrategy( //'admin' strategy
function(username, password, done) {
Admin.findOne(/* ... */)
