LLDAP

LLDAP is a lightweight, deliberately simplified LDAP directory for authentication. A web interface manages users, groups and custom attributes and lets people manage their own account data and reset passwords via email.

The actively maintained software is self-hosted, built with Rust and supports SQLite, PostgreSQL and MySQL or MariaDB. It is licensed under GPL v3. Single sign-on via modern protocols requires an additional service such as Authelia or authentik.
