- Rewrite docs/index.md as a short landing page (what it is, screenshots, why this over the alternatives, features, a minimal "get it" snippet) instead of a full documentation dump — full docs live in the repo (README, docs/*.md) and are linked from here. - Cross-link to Proxy and theta-env's own Pages sites. - Screenshots are now clickable (open full size) on both the Pages site and the README. - Disable show_downloads in docs/_config.yml — the Cayman theme's "Download .zip/.tar.gz" buttons are gone; "View on GitHub" (which links back to the repo) is the only header link now.

SSO Manager
A self-hosted OpenID Connect provider with a bundled OpenLDAP directory and a web management UI — for home labs and small businesses that want their own identity provider instead of a hosted one.
One place to manage your users and groups, one login (OIDC) your modern apps can use, and one LDAP directory your older or odder apps can bind to directly. Everything runs on your own hardware; no phone-home, no hosted control plane, no per-user pricing.
Part of the theta42 self-hosted identity stack, alongside Proxy (an OIDC + LDAP-aware reverse proxy) and theta-env (the two composed with one command).

Why this over the alternatives
Tools like Keycloak, Authentik, Authelia, or Zitadel are OIDC providers, but LDAP is either a paid feature, a federation target you have to run separately, or absent. If your stack already has apps that speak LDAP directly — or you just want one real directory as the source of truth — you end up running two identity systems and keeping them in sync.
SSO Manager bundles the OpenLDAP directory with the OIDC provider, so OIDC apps and LDAP apps read from the same users and groups. The trade-off is scope: it's intentionally small and self-hosted, not an enterprise IAM suite. If you want a lightweight, self-contained identity provider with a real LDAP backend, that's the niche.
Features
- OpenID Connect / OAuth 2.0 provider — your own access/refresh/ID
tokens; standard discovery document at
/.well-known/openid-configuration. - Bundled OpenLDAP directory — users, groups, POSIX accounts, SSH public
keys, and sudo roles, with
memberOf+ referential-integrity overlays. - Web management UI — users, groups, and OAuth clients from a browser; invite and password-reset flows over email; self-service profile + API tokens.
- LDAPS for legacy apps — anything that binds LDAP directly (Gitea, Emby, …) uses LDAPS/StartTLS against the same directory.
- All-in-one Docker image — app + OpenLDAP + Redis in one container, or
run the pieces separately via
app_*env config.
Get it
git clone https://github.com/theta42/sso-manager-node.git
cd sso-manager-node
cp secrets.js.example nodejs/conf/secrets.js # edit it, or use app_* env
docker compose up -d --build
That's the standalone quick start. For the full set of install options
(Docker, bare-metal, or as part of the combined SSO + proxy stack), the
app_* env reference, and the OAuth/LDAP internals, see the
GitHub repository.
