I followed several options connecting to mongodb hosted by MongoLab but no success. I have tried both options providing the complete connection string like mongodb://:@ds029827.mongolab.com:29827/mongotest and also giving the username,password etc seperate in services tab. I have verified the connection to mongolab using java driver and it was successful. Error I am getting on the Roles tab. DreamFactory Utility Module Unexpected MongoDb Service Exception: Failed to connect to: [ds029827.mongolab.com:29827](http://ds029827.mongolab.com:29827): Authentication failed on database ‘mongotest’ with username ‘admin’: auth failed Kindly provide insights if any steps are missing. ---

Hi Abhijeet. Is this on the hosted DreamFactory system ([cloud.dreamfactory.com](https://cloud.dreamfactory.com) or [enterprise.dreamfactory.com](https://enterprise.dreamfactory.com) ?) If so, please know that we had an issue with an out of date driver. This is issue was resolved today and mongodb access should be available as per normal connection settings.
