Java/Mongodb authentication

Question

I saw a lot of tutorials showing how to auth in mongodb using Java

I have my mongodb configured with auth enabled. In console I use

use admin

db.auth("myUser","newPassword") and works well.

and in java In every sites visited the code is

Mongo mongo = new Mongo("localhost", 27017);
DB db = mongo.getDB("myBase");

boolean auth = db.authenticate("myUser", "newPassword".toCharArray());
    //auth is true if everithing went well

The BIG problem is that code doesn't work for me and I don't know why. I tested changing explicitly to admin database.

Mongo mongo = new Mongo("localhost", 27017);
DB db = mongo.getDB("admin");

boolean auth = db.authenticate("myUser", "newPassword".toCharArray());
DB db = mongo.getDB("myBase");
    //auth is true if everithing went well

This works BUT for me it is not a solution because I triying to use mongo with mule and the problem is that I can't be changing between db's for each auth which I must do.

WHY the first code works for all the people instead of me?

I realized what is the problem.

It seems that mongo work using user for each DB stored in the DB itself. I created the user in the same db and it works. It a very weird feature because I will have a lot of duplicated users in mongo, one for each DB that I have. Minus one for user managing in Mongo...

I was going to mention that possibility so I'm glad you found it. 2.6 is reworking auth a fair bit so it might not hurt to look at those upcoming changes.

That method is now deprecated. The new, preferred way is to us MongoClient(List<ServerAddress> seeds, List<MongoCredential> credentialsList) to create a client which will authenticate all connections to server

I don't think that would be the problem, because I'm using mule and internally it uses db.authenticate(username, password.toCharArray()) check github.com/mulesoft/mongo-connector/blob/master/src/main/java/… line 1257

Maybe could be a mongo config issue?

an error added but it isn't very important if you read carefully what is the issue
