rmongodb authentication problem

[pargentieri]

I'm trying to login using rmongodb and it does not authenticate.

However, if I open a mongo shell on my computer and type: mongo "url" -u 'username' -p 'password' it works!!

I think that the problem is this: https://stackoverflow.com/questions/31065196/rmongodb-support-for-mongodb-3 The rmongodb package is too old. Would it be possible to replace rmongodb with mongolite?
