MongoDB Authentifizierung Fehler von Mongo Java Client

Question

Ich habe versucht, eine Verbindung zu Mongo Db Version 3.2 mit Mongo Java Client Version 3.2 und die folgende Ausnahme erhalten, jede Idee, was hier schief gelaufen?

com.mongodb.MongoSecurityException: Exception authenticating 
at com.mongodb.connection.NativeAuthenticator.authenticate(NativeAuthenticator.java:48) 
at com.mongodb.connection.InternalStreamConnectionInitializer.authenticateAll(InternalStreamConnectionInitializer.java:99)

Folgendes ist der Code, den ich verwendete, um zu verbinden.

MongoClient mongoClient = null; 

    try { 
     MongoCredential credential = MongoCredential.createMongoCRCredential("admin", "mydatabase", "admin123".toCharArray()); 
     mongoClient = new MongoClient(new ServerAddress("10.100.5.41", 27017), Arrays.asList(credential)); 

     MongoDatabase database = mongoClient.getDatabase("mydatabase"); 
     System.out.println(database.getName()); 
     MongoCollection collection = database.getCollection("user"); 

     MongoCursor cursor = collection.find().iterator(); 
     while (cursor.hasNext()) { 
      System.out.println(cursor.next()); 
     } 

    } catch (Exception e) { 
     e.printStackTrace(); 
    }

Nach Stunden der Fehlersuche, db Administrator sagte, dass er den Benutzernamen und das Passwort geändert hat. Manchmal frage ich mich, warum ich Software Engineer werde.
