The GitHub Pages site used the generic jekyll-theme-cayman theme -- purple gradient hero, no site nav, no per-page SEO. Replaced with a custom layout that mirrors the actual app UI: dark fixed navbar with the theta42 logo, Bootstrap 5 + Font Awesome (same stack the app uses), content in a card, dark footer matching bottom.ejs (copyright, MIT license, GitHub, Changelog links). - New cross-page nav (Home/Deployment/Configuration/OAuth/LDAP/ Changelog) -- there was previously no way to get from one docs page to another except a single "Back to Home" link per page. - SEO: jekyll-seo-tag + jekyll-sitemap (both GitHub-Pages-supported plugins, no custom build needed) -- real per-page meta description, Open Graph/Twitter card tags, canonical URLs, JSON-LD, sitemap.xml, and a robots.txt referencing it. Added a real description to every page's front matter (none existed before). - Mobile: Bootstrap's responsive grid + collapsible navbar; the screenshot pairs in index.md (inline width="49%" for a two-up desktop layout) now stack to full-width below 576px instead of squeezing illegibly small. Verified with a real Jekyll build (jekyll/jekyll Docker image, no Ruby available locally) + Playwright: desktop and mobile (375px) screenshots of the home and deployment pages, mobile nav toggle open/close, active-link highlighting per page, zero console/page errors, and confirmed real SEO output (meta description, OG/Twitter tags, canonical, JSON-LD, sitemap.xml, robots.txt) via curl against the served site.

# OAuth 2.0 / OpenID Connect
|
|
|
|
[← Back to Home](index.html)
|
|
|
|
SSO Manager is an **OpenID Connect / OAuth 2.0 provider**: it issues its own
|
|
access, refresh, and ID tokens that your apps can consume to authenticate
|
|
users and authorize API calls. It also runs a full OpenLDAP directory, so it
|
|
can be both your SSO and your user directory at once.
|
|
|
|
## Discovery
|
|
|
|
The provider publishes a standards-compliant discovery document:
|
|
|
|
```
|
|
GET https://<sso-host>/.well-known/openid-configuration
|
|
```
|
|
|
|
It advertises the `issuer`, `authorization_endpoint`, `token_endpoint`,
|
|
`userinfo_endpoint`, `end_session_endpoint`, supported scopes, and token
|
|
lifetimes. OIDC clients (e.g. the theta42/proxy) can read their endpoint URLs
|
|
from here rather than configuring each one.
|
|
|
|
The `issuer` advertised is `conf.oauth.issuer` — set it to the **browser-facing**
|
|
HTTPS URL the SSO is served at (e.g. `https://sso.example.com`), either in
|
|
`conf/secrets.js` or via `app_oauth__issuer` / `OAUTH_ISSUER`.
|
|
|
|
## OAuth clients
|
|
|
|
An OAuth client represents an app that authenticates against the SSO. Each has:
|
|
|
|
- `client_id` (UUID) + `client_secret` (bcrypt-hashed; the **raw secret is
|
|
shown once** when the client is created or rotated — save it immediately).
|
|
- `name`, `description`, `created_by` (the admin uid that created it).
|
|
- `redirect_uris` — allowed callback URLs. Each entry matches exactly, or may
|
|
use `*` (one hostname label) / `**` (any number of labels) as a wildcard —
|
|
e.g. `https://*.example.com/__proxy_auth/callback` covers every host
|
|
theta42/proxy fronts under `example.com`, so you don't have to register
|
|
each proxied host's callback individually.
|
|
- `scopes` — requested scopes (default `openid profile email groups`).
|
|
- `allowed_groups` — restrict the client to members of specific SSO groups
|
|
(empty = any valid user).
|
|
- `token_lifetime` — `access_token` / `refresh_token` lifetimes (seconds).
|
|
|
|
### Managing clients
|
|
|
|
Clients are managed from the web UI (as a member of the `app_sso_oauth_admin`
|
|
group) or the HTTP API at `/api/oauth/client` (auth via the `auth-token` header
|
|
from a login):
|
|
|
|
| Method | Path | Action |
|
|
|--------|------|--------|
|
|
| `GET` | `/api/oauth/client` | list clients |
|
|
| `POST` | `/api/oauth/client` | create a client (returns the raw `client_secret` once) |
|
|
| `GET` | `/api/oauth/client/:id` | get one |
|
|
| `PUT` | `/api/oauth/client/:id` | update redirect URIs / scopes / groups |
|
|
| `DELETE` | `/api/oauth/client/:id` | delete |
|
|
| `POST` | `/api/oauth/client/:id/rotate` | rotate the secret (returns the new raw secret once) |
|
|
|
|
> All client-management endpoints are gated by the `app_sso_oauth_admin` group.
|
|
|
|
## Scopes
|
|
|
|
| Scope | Claims / access |
|
|
|-------|-----------------|
|
|
| `openid` | OIDC ID token + discovery |
|
|
| `profile` | `preferred_username`, display name, etc. |
|
|
| `email` | the user's `mail` |
|
|
| `groups` | the user's group memberships (the `groups` claim) |
|
|
|
|
The `groups` claim is what relying parties (e.g. the proxy's
|
|
`app_auth__adminGroups`) use to map group membership to roles.
|
|
|
|
## Token lifetimes
|
|
|
|
Defaults (overridable per-client via `token_lifetime`, or globally via
|
|
`app_oauth__token_lifetime__access_token` /
|
|
`app_oauth__token_lifetime__refresh_token`):
|
|
|
|
- access token: 3600s (1 hour)
|
|
- refresh token: 2592000s (30 days)
|
|
|
|
## Admin gating
|
|
|
|
SSO admin actions are gated by LDAP group membership (checked via the group's
|
|
`member` list, not `memberOf` on the user):
|
|
|
|
- `app_sso_admin` — full admin (users, groups, settings).
|
|
- `app_sso_oauth_admin` — OAuth client management.
|
|
- `app_sso_invite` — invitation management.
|
|
|
|
The bootstrap in [theta-env](https://github.com/theta42/theta-env) creates your
|
|
first admin and adds them to `app_sso_admin` + `app_sso_oauth_admin`
|
|
automatically; for a standalone install, add the admin's DN to those groups
|
|
manually (or via `ops/ldap-setup.sh`).
|
|
|
|
## JWT signing
|
|
|
|
Tokens are signed with `conf.oauth.jwtSecret` (`app_oauth__jwtSecret` /
|
|
`JWT_SECRET`). **Persist this secret** — if it changes, every issued token
|
|
stops validating. The all-in-one Docker image auto-generates one if none is set,
|
|
but that generated value does not survive container recreation unless you
|
|
persist it (set `JWT_SECRET` in your `.env`).
