I'm currently trying to setup LDAP syncing with my local Authentik instance.
I created everything needed to make LDAP queries and tested querying the server from the Homarr container, here's the following command I used from a shell attached to the Homarr docker container that returned the list of users in my LDAP server:
Because I currently have two layers of security, one for accessing the app (forward auth) which was already configured, and one for logging in and modifying boards (LDAP). Authentik doesn't allow for backchannel (secondary) providers for OIDC so I gave LDAP a shot. Now that you mention it, it might be a good idea to migrate both into a single OIDC provider if it's better supported by Homarr.
