Parse-Server mongoerror authentication failed
<p>I setup a local parse-server, it is working perfectly fine except when I enable authentication in MongoDB and change connection string to <code>mongodb://username:password@localhost:27017/dbname</code>, the parse console throw the following error:</p>

<p><code>unable to ensure uniqueness for usernames mongoerror authentication failed</code></p>

<p>The client i.e. RoboMongo works fine too, with authentication. I even tried with a user that has both <code>userAdminAnyDatabase</code> and <code>dbAdminAnyDatabase</code> roles assigned to it just to ensure it is not a permission issue.</p>

<p>Update:
I was using MongoDB 3.2 so I tried to downgrade to MongoDB 3.0.12, still the same issue.</p>

<p>Update 2:
I even tried <code>root</code> role which has the highest privilege i.e. superuser but still no luck. </p>
