Mongo : db.auth() fails on windows - mongodb

Question

I'm trying to run a mongo instance on a windows container.
I have found this answer regarding authentication but I does not work for me
MongoDB: Server has startup warnings ''Access control is not enabled for the database''
I have a cfg file which I'm using to start mongo, my image is based on an existing mongo docker image on top of which I'm just copying my config file amd I'm trying to instruct mongo to use it. I actually don't know if it really does this, but as far as I know the base image CMD is overriden with my new CMD.
This is the dockerfile
FROM mongo:windowsservercore-1809
WORKDIR c:\
COPY .\mongod.Win.cfg .
CMD ["mongod", "--auth", "-f", "mongod.Win.cfg"]
And this is my mongod.win.cfg
storage:
dbPath: C:\data\db
journal:
enabled: true
security:
authorization: enabled
And I'm building the image in a docker-compose
invoice_db:
build:
context: ./Invoice.Db
dockerfile: ./mongo.win.Dockerfile
image: mongo:v1
container_name: invoice-db
ports:
- 27017:27017
environment:
MONGO_INITDB_ROOT_USERNAME: "admin"
MONGO_INITDB_ROOT_PASSWORD: "pass"
volumes:
- invoice-data-volume:c:\data\db
restart: unless-stopped
volumes:
invoice-data-volume:
name: invoice-data
When I ssh in the container and try to login as admin with the password pass I get this
PS C:\> mongo

Can someone help me figure out this ?

try with:
db.auth({user:"admin", pwd:"pass", mechanism:"SCRAM"})
