Could not find/access authentication database HOMSReport


I am trying to add my first external dataSource (local MongoDB) to dremio.
But no matter how I try it always reports “could not access”.
Tried with mongo command the connection seems all right.
I think somewhere my settings not right as you guys heavily use Mongo for testing.
Can anyone give some help?


@Hao Is the Dremio coordinator and executor IP’s white listed on the MongoDB side?

Thanks @balaji.ramaswamy

I am not using cloud-hosted MongoDB service, the mongo service and Dremio are all running at same machine.
I’ve never seen white list for my MongoDB.
