Cannot connect with MongoLab

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: 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 or 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If so, please know that we had an issue with an out of date driver.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.
