LLDAP is a lightweight user directory that lets all your self-hosted apps share one set of accounts and passwords. It speaks just enough LDAP for Nextcloud, Jellyfin, Gitea, GitLab, Grafana, Home Assistant, Proxmox VE, Vaultwarden, and many more to authenticate users against a single source of truth, with ready-made example configurations for more than 80 services. Day-to-day administration happens in a web interface where you create users, set passwords, upload avatars, build groups, and add members from a dropdown. Regular users can sign in to edit their own profile, and once SMTP is configured they can request a password-reset link by email instead of pinging the admin. Custom attributes (text, numbers, dates, or JPEG photos) are defined on the user and group schema pages, which unlocks integrations that expect fields such as uidNumber or homeDirectory, including Linux logins through PAM. Three built-in groups keep privileges tidy: lldap_admin for full control, lldap_password_manager for password resets, and lldap_strict_readonly for read-only service accounts. Group membership is exposed through memberOf filters, LDAPS secures connections when you expose the port, and a GraphQL API plus a bootstrap script let you manage users, groups, and attributes declaratively from JSON files. Pair it with Authelia, Authentik, or Keycloak when you also want single sign-on and multi-factor prompts.
