> +Question:+
> Fiware IoT Agent JSON connection to MongoDB with authentication
> +Description:+
> I'm trying to configure the Fiware IOT Agent Json connection to MongoDB with authentication, but I always get the Authentication Failed error.
> I'm running the services via docker-compose, and in the Fiware IOT Agent JSON I have the environment variables IOTA_MONGO_USER and IOTA_MONGO_PASSWORD defined, which correspond to the mongodb username and password.
> Here I put some parts of my docker-compose:
>  iot-agent:
>     image: fiware/iotagent-json:latest
>     hostname: iot-agent
>     container_name: fiware-iot-agent
>     depends_on:
>         - mongo-db
>     networks:
>         - fiware
>     ports:
>         - "4041:4041" 
>         - "7896:7896"
>     environment:
>         - IOTA_MONGO_HOST=mongo-db
>         - IOTA_MONGO_PORT=${MONGO_DB_PORT}
>         - IOTA_MONGO_USER=${MONGO_USER}
>         - IOTA_MONGO_PASSWORD=${MONGO_PWD}
>         - IOTA_MONGO_DB=iotagentul
>  mongo-db:
>     image: mongo:${MONGO_DB_VERSION}
>     hostname: mongo-db
>     container_name: db-mongo
>     expose:
>         - "${MONGO_DB_PORT}"
>     ports:
>         - "${MONGO_DB_PORT}:${MONGO_DB_PORT}" # localhost:27017
>     networks:
>         - fiware
>     volumes:
>         -  ./volumes/mongo-db/db:/data/db
>     environment:
>         - MONGO_INITDB_ROOT_USERNAME=${MONGO_USER}
>         - MONGO_INITDB_ROOT_PASSWORD=${MONGO_PWD}
> The error log is this:
> (Note: the user and password in the fields below appears fine, I removed it from the post for security)
