Hello

On an Ubuntu installation (VERSION=«&nbsp;20.04.3 LTS (Focal Fossa)&nbsp;»), Odroid card, I installed Gladys Assistant. When trying to install ZigBee to MQTT, I noticed that it doesn’t work

The 2 containers are launched

```auto
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
91862eef2c3b koenkk/zigbee2mqtt:latest "docker-entrypoint.s…" 34 minutes ago Up 5 seconds gladys-z2m-zigbee2mqtt
ad8ff539547e eclipse-mosquitto:2 "/docker-entrypoint.…" 37 minutes ago Up 37 minutes gladys-z2m-mqtt
485cf29283e0 gladysassistant/gladys:latest "docker-entrypoint.s…" 42 minutes ago Up 42 minutes gladys

```

but communication is not happening (red crosses in Gladys)

Looking at the logs, we see that

```auto
Using '/app/data' as data directory
Zigbee2MQTT:info 2022-01-29 15:04:21: Logging to console and directory: '/app/data/log/2022-01-29.15-04-18' filename: log.txt

```

and

```auto

1643470019: Client gladys-main-instance-636325 disconnected, not authorised.

```

If I look at the mosquitto configuration, we see that

```auto
# cat /mosquitto/config/mosquitto.conf
listener 1884
allow_anonymous **false**
# connection_messages false
password_file /mosquitto/config/mosquitto.passwd

```

My question is: how can we set allow\_anonymous to True in Docker in a permanent way (easy solution, but not very secure) or use the mosquitto users (and the mosquitto\_passwd command)?

Thanks in advance
