So I changed the authentication to http and I could not login using the Web Interface. I received the following error:

“Error 403 – Forbidden

You don’t have permission to access this page [HTTP Remote-User= ; Remote IP address=172.17.0.1]”

Solution:

1. ~ > sudo docker exec -t -i 324e7833ba21 /bin/bash (to browse the docker container config files)
2. apt-get update && apt-get install vim (to be able to modify config files)
3. vim ./data/config.php
4. Change the variable ‘auth_type’ => ‘none’
5. Login and rechange the authentication to web form
