How to serialize/deserialize multiple local strategie

Question

How can I serialize/deserialize multiple local strategies: I have already tried this Use multiple local strategies in PassportJS but not success.

This is my code :

passport.use('user', new LocalStrategy( function(username, password, done) {
    UserSchema.findOne({ username: username }, function(err, user) { 
    // ...
       return done(null, user);
    });
}));

passport.use('admin', new LocalStrategy( function(username, password, done) {
    adminSchema.findOne({ username: username }, function(err, user) {
    // ...
        return done(null, user);
    });
}));

passport.serializeUser(function(user, done){
     done(null, user.id);
});

passport.deserializeUser(function(id, done){
   adminSchema.findById(id, function(err, user){
     if(err) done(err);
       if(user){
         done(null, user);
       } else {
          user.findById(id, function(err, user){
          if(err) done(err);
          done(null, user);
       })
   }
});

I was working on the same problem. I took your code and changed a few things and it worked for me! Make sure to log out of one account before trying another or just use an incognito tab.

Here is the updated code I used:

passport.use('user', new LocalStrategy( function(username, password, done) {
    UserSchema.findOne({ username: username }, function(err, user) { 
    // ...
       return done(null, user);
    });
}));

passport.use('admin', new LocalStrategy( function(username, password, done) {
    adminSchema.findOne({ username: username }, function(err, user) {
    // ...
        return done(null, user);
    });
}));

passport.serializeUser(function(user, done){
     done(null, user.id);
});

passport.deserializeUser(function(id, done){
   adminSchema.findById(id, function(err, user){
     if(err) done(err);
       if(user){
         done(null, user);
       } else {
          UserSchema.findById(id, function(err, user){
          if(err) done(err);
          done(null, user);
       })
   }
});

My schema names are different so I changed them to match yours. One issue you might have is using UserSchema instead of userSchema. Try that next if it doesn't work.

Hope this helps!

Is there anyway the User need not Logout? Am talking about a real time scalable application. Where say multiple admins and users are able to login. — godimedia, Feb 20 '15 at 09:35
