add support for Mongo 4 SCRAM authentication #15
Description
I'll make a ticket for this, though I don't have a patch. It may save someone else a little hassle when searching.
This driver is incompatible with Mongo 4.0 authentication. This means that user/passwords for MongoDb 4.0 will not work.
Per this link
https://docs.mongodb.com/manual/release-notes/4.0-compatibility/#remove-support-for-mongodb-cr
"Starting in version 4.0, MongoDB removes support for the deprecated MongoDB Challenge-Response (MONGODB-CR) authentication mechanism."
The driver should support Salted Challenge Response Authentication Mechanism (SCRAM), the default authentication mechanism.
Note that the driver appears to be compatible (after adding the patch in #14) with MongoDb 4.0 if no authentication is required.
