Heroku Mongo Authentication

[bbrock25]

When using the Heroku and MongoLabs for running this application, we're getting failure when trying to authenticate the user.

This doesn't reproduce locally, most likely due to differences in the mongo versions. I'm running mongo v3.0.6 locally.

Has anyone else been experiencing this issue?

I just ran into the same issue. It looks like mongo-mapper hasn't been well maintained with the latest release in November 2014. The mongo dependency mongo-mapper uses (https://github.com/mongomapper/mongomapper/blob/master/gemfiles/Gemfile.common.rb#L10) is most likely not compatible with MongoLabs 3.x DBs
