christkv:
no need you can use DEFAULT as the auth mechanism and mongodb-core does it for you.

kangas:
@christkv is DEFAULT auth mechanism mentioned in the docs? Don't see it here. Mentioned else where? http://mongodb.github.io/node-mongodb-native/2.0/reference/connecting/authenticating/

christkv:
It could well be missing from the docs can you open a node ticket so I
don't forget ?
