Can't create new roles using mosquitto dynamic security Connection error: Not authorized

Question

The permissions on my dynamic-security.json file is the following:

-rw-r--r-- 1 mosquitto mosquitto 1247 Mar  6 06:51 dynamic-security.json

After trying to add a new role:

mosquitto_ctrl -u myadmin -P admin333 dynsec createRole firstRole

Also tried:

sudo mosquitto_ctrl -u myadmin -P <mypassword> dynsec createRole firstRole

I also tried it with all permissions allowed, and with the owner being the root. It all gave me the same error.

Connection error: Not authorized

The dynamic-security.json file was generated with:

sudo mosquitto_ctrl dynsec init /var/lib/mosquitto/dynamic-security.json myadmin

And this is the contents of the mosquitto.conf file:

persistence true
persistence_location /etc/mosquitto/data
user mosquitto
listener 1883
per_listener_settings false
allow_anonymous false 
password_file /etc/mosquitto/conf.d/credentials
log_dest file /etc/mosquitto/log/mosquitto.log
log_dest stdout
plugin /usr/lib/x86_64-linux-gnu/mosquitto_dynamic_security.so
plugin_opt_config_file /usr/lib/x86_64-linux-gnu/dynamic-security.json

Answer 1

Changed the plugin_opt_config_file location in the mosquitto.conf file:

plugin_opt_config_file /etc/mosquitto/dynamic-security.json

I have also removed the old dynamic-security.json file and created a new one in the new location using:

sudo mosquitto_ctrl dynsec init /etc/mosquitto/dynamic-security.json myadmin

And then most importantly, i restarted the mosquitto.service. Now it works fine!
