If you want to keep your LDAP as the source of truth, then Keycloak is also a very good option. I did that originally, but decided I only had a couple of things needing LDAP and that wasn’t worth keeping it around. Authentik was a good way to emulate an LDAP but with a different back end. But Keycloak is definitely my recommendation in your case.
