Theta Directory

A production-grade, self-hosted OpenID Connect provider, Resource Directory & IAM Engine, and bundled OpenLDAP directory with a modern web console — designed for home-labs and enterprise infrastructure that demand total sovereignty over their identity, secrets, and resource catalog.

It provides a single source of truth for identity (OIDC + LDAP), host/service directory inventory, access control groups, and secrets management running entirely on your own hardware without third-party cloud lock-in.

Theta Directory is deployed as part of Theta Suite, alongside Theta Proxy and Theta Gateway — it isn't installed or run on its own. ./setup.sh wires the whole stack together automatically.

Features

• OpenID Connect / OAuth 2.0 provider — issue your own access, refresh, and ID tokens; protect your apps with standard OIDC login. Discovery document at /.well-known/openid-configuration.
• Bundled OpenLDAP directory — users, groups, POSIX accounts (posixAccount/inetOrgPerson), SSH public keys, and sudo roles, with memberOf + referential-integrity overlays. This is your single source of truth for identity, not a sidecar.
• Web management UI — manage users, groups, and OAuth clients from a browser; invite and password-reset flows over email; user self-service for profile and API tokens.
• Direct LDAP binds — Linux hosts (PAM/SSSD login, LDAP-backed sudo rules, SSH public keys via openssh-lpk) and LDAP-native apps (Gitea, Emby, and anything else that speaks LDAP) use LDAPS (636) or StartTLS against the same directory, so you don't maintain a second user database for them.
• Personal access tokens — any user can mint a long-lived bearer token to drive the management API from scripts or CI, scoped to their own permissions.
• Directory & Inventory Graph — full host/service/site graph with resource metadata, automatic LDAP group provisioning (_access / _admin), and Access Request workflows.
• Subtype Management & Metrics Drivers Engine — 4-tier resolution engine binding subType metadata (systemd, docker, proxmox, wireguard, postgresql, redis, k8s) to operational telemetry, log streaming, and remote lifecycle control.
• Explicit Secret Inheritance Mode — OpenBao KV-v2 integration with strict upward ancestor lineage (Resource -> Host -> Cluster -> Site), preserving precise secret scoping across services and containers.
• Multi-Site Support (Geo-Location Scaling) — built-in support for N-Way Multi-Master OpenLDAP replication across physical sites for HA and low latency.

Secrets

Secrets are loaded from OpenBao at boot via @simpleworkjs/bao-conf, which deep-merges secret/sso-manager/conf over the file-loaded config (fail-soft: if OpenBao is unreachable, boot continues from CONF_SECRETS). The SSO authenticates to OpenBao with the scoped VAULT_TOKEN (env, policy sso-broker) — never the root token.

The SSO also acts as the vault broker for the whole stack: it mints per-user (user-<uid>) and per-admin (sso-admin) tokens through the sso-broker token role and exposes the personal-secrets UI at Vault → My Secrets (secret/users/<uid>/*, server-side token injection + path-scope guard) and an admin Apps tab to mint scoped tokens for external apps (secret/apps/<name>/*). The old utils/conf_manager.js was replaced by @simpleworkjs/bao-conf; the admin Configuration UI (/api/conf) now writes secret/sso-manager/conf through bao-conf.set.

The config/*-secrets.js files are operator-edit seed artifacts (gitignored), not the authoritative store. For the full architecture, policies, token model, and rotation procedure, see theta-suite's Secrets docs.

Documentation

The nitty LDAP details (overlay setup, the custom theta42Person schema, the required groups, LDAPS/TLS, direct-bind service accounts) live in:

• DEPLOYMENT.md — Docker + bare metal, the config layers, the app_* env reference, LDAPS/TLS, backups, troubleshooting.
• API.md — the management API.
• docs/ — the same content broken into OAuth/OIDC and LDAP, also published at the unified theta-suite docs site.
• CHANGELOG.md — what changed in each release.
• All of the above is also readable from the running app itself at /docs — no internet access required.
