title: MongoDB 2.6.12 - no collections in DB
body: <p>I have a some problem with MongoDB (2.6.12). I have one database with collections and a lot of data. Then I created user with <code>readWrite</code> role, enabled <code>auth=true</code> in <code>mongod.conf</code>, restarted 'mongod' service.</p>
  
  <p>Looks like auth works fine, but I can't see any data/collections in DB. I can't use 'find' query, in mongo shell it just returns nothing (empty line). I also can connect to DB without credentials and I see the same result. </p>
  
  <p>I've tried a different roles and different users, but I can't get access to my data. What can be a problem?</p>
