So I am trying to use LLDAP as a authentication backend for Authelia, but I am getting this error:

level=error msg="Failure running the user provider startup check: bind failed with error: LDAP Result Code 64 \"Naming Violation\": Not a subtree of the base tree" stack="github.com/authelia/authelia/v4/internal/commands/root.go:287

Everything is running in a docker swarm setup behind traefik. Both containers are on the same docker network. This is the LLDAP setup using Ansible, so everything inside a double curly brackets is refering to a variable. I have replaced my domain with example.org https://pastebin.com/8VqmrEaP And this is the authentication config in authelia https://pastebin.com/Lg1abMTw Has anyone seen this before, or is able to see what is wrong?

Hey! Have you checked the LLDAP logs? The error should be richer on the LLDAP side

The LLDAP container only has this as log. The last lines repeat somewhat. Is there any other logs, or debug options? https://pastebin.com/iULM7gd1

You can set verbose=true in the config

Okay, will try that.

The Devil is in the details -- or in this case, in the redacted text: the error tells you that the bind DN, the admin username you configured in authelia, is not in the same DC as the one you configured in LLDAP.

Think I found my mistake.... Had used the variable LLDAP_BASE_DN instead of LLDAP_LDAP_BASE_DN Need to go over and fix those. Thanks for the help!

My pleasure! It's always useful to see the config as it's parsed, not just in the config file/env variables
