LDAP server options

I’m looking to mostly use Keycloak to do authentication for my self hosted services. However, some services such as Jellyfin do not support it. I’m looking for a simple LDAP server that can act as a backend for Keycloak. Ideally I would like to do all of the administration from Keycloak but I’m not sure that is possible.

At the moment I’m looking as Samba AD but that feels overkill. I don’t need certificates or DNS all I need is basic ldaps.

Update:

I’m going to setup a VM with step-ca, Keycloak and LLDAP

This plugin is WIP but supports Keycloak:

Have you tried it?
