When you connect MongoDB with auth you need to specify the "Authentication Mechanisms". If your MongoDB version is 3.0+ the default "Authentication Mechanisms" is SCRAM-SHA-1, for other versions MONGODB-CR as the default.
db.auth()
The db.auth() method with mechanisms example:
db.auth( {
user: <username>,
pwd: <password>,
mechanism: <authentication mechanism>
} )
command line (SCRAM-SHA-1 as default)
mongo host:port/<database_name> -u "<user_name>" -p "<user_pwd>" --authenticationDatabase "<auth_db>" --authenticationMechanism "SCRAM-SHA-1"
