LDAP Plugin not working

[gianmarcomurru 2]

Hello! 

I am trying to configure the LDAP Plugin to work without success.

I have an Emby server and my LDAP server deployed as a docker container, they have access to the same docker network. I have ensured that the Emby container can reach the LDAP one successfully.
 

These are my settings on the LDAP Plugin:

If I run this from a docker container in the same network (I couldn’t install the required package openldap-clients on the Emby server container). As you see these settings are working here:

 

These are the logs related to the login attempt

Hi there, it looks like the ldap server is rejecting the login, no?

Seems so but it’s quite hard to debug it. I logged in with the same credentials from a ldap client and I have the same setup on Jellyfin working fine. The LDAP server is reachable and the credentials are correct. Still throw that error, do you have perhaps suggestions on how debug it?

Any suggestion @Luke?

Are you able to get any logging or debug info from the LDAP server?

Also can you try this version of the LDAP plugin? We haven't updated the embedded ldap library in a while, so that's worth a shot:

LDAP.zip

Thanks.

Hey!

After debugging more, I found this issue which was the user search filter. 

Here's the step I ran:

Run a container to test LDAP queries:

docker run -it --rm ubuntu /bin/bash # add <--network your_ldap_docker_network> if using a custom network

Run these to test your query:

apt-get update && apt-get install -y ldap-utils

ldapsearch \
  -x \
  -H ldap://authentik_ldap:3389 \
  -p 3389 \
  -w 'your_password' -D 'cn=bind_username,ou=users,DC=ldap,DC=goauthentik,DC=io' \
  -b 'OU=users,DC=ldap,DC=goauthentik,DC=io' \
  '(cn=username_of_user_you_are_looking_for)'

If you are using Authentik, these are the settings I am using:

@Lukethank you very much for your help and patience!
