[Jeff-Tian]

Need support to connect mongo db by mongodb://username:password@dds-xxx-pub.mongodb.rds.aliyuncs.com:3717,dds-yyy-pub.mongodb.rds.aliyuncs.com:3717/dbname?replicaSet=mgset-123.

Current it fails:

@Jeff-Tian Thanks for the heads up. I need to revisit this application and give it a major face lift. Will include a fix for the issue described
