Cannot log in to Mongo from command line - using MongoDB 3.0 and WiredTiger
I've had the same authentication issue on an MMS deployed db (though it has nothing to do with it).


it tries to connect to /test by default. If you want another database, just specify it, e.g. 102.216.73.164/foo.
upgrade your mongo shell to 3.0.3 (you currently use 2.6.6). That solved the problem for me.
