I am building a R script in which I need to connect to MongoDB through authentication and process the data fetched from database using rmongodb package.For that I have created a new MongoDB user in version 3.0.4 and while connecting to mongoDB from R script authentication fails. Also the user is authenticated successfully through mongo shell. Also authentication works fine while I authenticate user created in MongoDB version 2.x.
Following is code snippet which we have used in R script to connect to Mongo database.
mongo <- mongo.create("127.0.0.1", "", "user", "pass", "db", 0L )
While executing above code snippet we receive the following response
error: Loading required package: rmongodb Authentication failed.
Please suggest me appropriate solution to authentication failure issue in rmongodb package.
