From 8aba2ab2e71717b6a1bed041bc4652ca8d104108 Mon Sep 17 00:00:00 2001 From: Yadd Date: Fri, 17 Apr 2026 12:10:54 +0200 Subject: [PATCH 01/10] feat(auth): add OpenID Connect authentication mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces AUTH_MODE=oidc alongside the existing token flow. In the new mode, humans authenticate via an external IdP (Authorization Code + PKCE) and receive an opaque httpOnly session cookie; programmatic clients keep using Bearer users.token. Backend: - New /auth/{login,callback,backchannel-logout,logout,me} routes - AuthMiddleware: oidc_sessions cookie lookup, users.token Bearer fallback, lazy access_token refresh with last_refresh_at short-circuit + SELECT FOR UPDATE, UI routes 302 to /auth/login, API routes 401 JSON - OIDC client based on Authlib (discovery, JWKS, token exchange, refresh, userinfo, logout_token verification) - Fernet-encrypted IdP tokens at rest; openrag_session cookie is opaque (SHA-256 hashed in oidc_sessions) - Back-channel logout: revokes by sid (spec-compliant) - User matching: external_user_id=sub (fast path) → email (with backfill of external_user_id=sub) → 403 (no auto-provisioning) Chainlit: - header_auth_callback reads openrag_session cookie in oidc mode - password_auth_callback gated behind AUTH_MODE!=oidc DB: - Alembic migration f5b6c918f741: users.email (unique nullable) + oidc_sessions table (encrypted tokens, sid index, composite user_sub) Deps: authlib>=1.3, itsdangerous>=2.2, cryptography>=42, respx (dev) Docs: - docs/oidc.md: full guide (flow, config, Keycloak + LemonLDAP::NG, programmatic access, back-channel logout, troubleshooting, security) - CLAUDE.md: Authentication section extended - README.md + .env.example Backward compat: - AUTH_MODE=token (default) behavior strictly unchanged - Legacy 403 "Missing token" / "Invalid token" responses preserved Pairs with linagora/openrag-admin-ui#18. --- .env.example | 24 + CLAUDE.md | 91 +++ README.md | 11 + docker-compose.yaml | 96 +-- docs/oidc.md | 739 ++++++++++++++++++ extern/indexer-ui | 2 +- openrag/api.py | 105 ++- openrag/app_front.py | 54 +- openrag/components/auth/__init__.py | 11 + openrag/components/auth/deps.py | 61 ++ openrag/components/auth/middleware.py | 234 ++++++ openrag/components/auth/oidc_client.py | 388 +++++++++ openrag/components/auth/refresh.py | 183 +++++ openrag/components/auth/session_tokens.py | 64 ++ openrag/components/auth/state_cookie.py | 55 ++ openrag/components/auth/test_middleware.py | 509 ++++++++++++ openrag/components/auth/test_oidc_client.py | 396 ++++++++++ .../components/auth/test_session_tokens.py | 69 ++ openrag/components/auth/test_state_cookie.py | 69 ++ openrag/components/indexer/vectordb/models.py | 30 + .../indexer/vectordb/test_oidc_sessions.py | 367 +++++++++ openrag/components/indexer/vectordb/utils.py | 289 ++++++- .../components/indexer/vectordb/vectordb.py | 70 ++ openrag/models/user.py | 1 + openrag/routers/auth.py | 547 +++++++++++++ openrag/routers/test_auth_router.py | 733 +++++++++++++++++ .../versions/f5b6c918f741_add_oidc_auth.py | 77 ++ pyproject.toml | 4 + tests/api_tests/OIDC_TEST_COVERAGE.md | 28 + tests/api_tests/test_oidc_lifecycle.py | 431 ++++++++++ 30 files changed, 5635 insertions(+), 103 deletions(-) create mode 100644 docs/oidc.md create mode 100644 openrag/components/auth/__init__.py create mode 100644 openrag/components/auth/deps.py create mode 100644 openrag/components/auth/middleware.py create mode 100644 openrag/components/auth/oidc_client.py create mode 100644 openrag/components/auth/refresh.py create mode 100644 openrag/components/auth/session_tokens.py create mode 100644 openrag/components/auth/state_cookie.py create mode 100644 openrag/components/auth/test_middleware.py create mode 100644 openrag/components/auth/test_oidc_client.py create mode 100644 openrag/components/auth/test_session_tokens.py create mode 100644 openrag/components/auth/test_state_cookie.py create mode 100644 openrag/components/indexer/vectordb/test_oidc_sessions.py create mode 100644 openrag/routers/auth.py create mode 100644 openrag/routers/test_auth_router.py create mode 100644 openrag/scripts/migrations/alembic/versions/f5b6c918f741_add_oidc_auth.py create mode 100644 tests/api_tests/OIDC_TEST_COVERAGE.md create mode 100644 tests/api_tests/test_oidc_lifecycle.py diff --git a/.env.example b/.env.example index aad7b0267..ec7cb71f3 100644 --- a/.env.example +++ b/.env.example @@ -66,3 +66,27 @@ LOG_LEVEL=DEBUG # See possible values https://loguru.readthedocs.io/en/stable/ap # SERVER # Set the preferred URL scheme for generated URLs (e.g., task_status_url).

When a user logs out from the IdP or an admin terminates their session, the IdP can notify OpenRag to revoke the session. + +### How It Works + +1. User logs out from Keycloak (or is logged out by admin) +2. Keycloak sends a `POST` request to `https://openrag.example.com/auth/backchannel-logout` with a signed JWT `logout_token` +3. OpenRag verifies the JWT signature and extracts the `sid` claim +4. All `oidc_sessions` rows with matching `sid` are marked `revoked_at = now()` +5. OpenRag responds with `200 OK` +6. Next time the user tries to use an old session cookie, the middleware sees `revoked_at` is set and redirects to login + +### IdP Configuration + +**Keycloak:** + +1. **Clients** → `openrag` → **Settings** +2. Enable **Backchannel logout session required**: ON +3. Set **Backchannel logout URL**: `https://openrag.example.com/auth/backchannel-logout` +4. Click **Save** + +**LemonLDAP::NG:** + +1. Set the backchannel logout URL in the relying party configuration +2. Consult LLNG docs for exact steps + +### Request Format + +The IdP sends: + +``` +POST /auth/backchannel-logout HTTP/1.1 +Host: openrag.example.com +Content-Type: application/x-www-form-urlencoded + +logout_token=eyJhbGc... +``` + +**`logout_token`** is a signed JWT with claims: +```json +{ + "iss": "https://idp.example.com/realms/openrag", + "sub": "user-sub", + "sid": "session-id", + "aud": "openrag", + "iat": 1234567890, + "exp": 1234571490, + "events": { + "http://schemas.openid.net/event/backchannel-logout": {} + } +} +``` + +OpenRag: +1. Fetches the IdP's JWKS (via auto-discovery) +2. Verifies the JWT signature, `iss`, `aud`, `exp`, `iat` +3. Checks the `events` claim contains the logout event +4. Extracts `sid` and revokes matching sessions +5. Returns `200 OK` or `400 Bad Request` if validation fails + +### Testing Back-Channel Logout + +Create a signed logout token manually (advanced): + +```python +import jwt +import json +from datetime import datetime, timedelta + +# Keycloak realm public key (from /.well-known/openid-configuration -> jwks_uri) +# For testing, sign with a private key + +payload = { + "iss": "https://idp.example.com/realms/openrag", + "sub": "user-sub", + "sid": "session-id-from-openrag", + "aud": "openrag", + "iat": int(datetime.utcnow().timestamp()), + "exp": int((datetime.utcnow() + timedelta(minutes=5)).timestamp()), + "events": { + "http://schemas.openid.net/event/backchannel-logout": {} + } +} + +token = jwt.encode(payload, "your-private-key", algorithm="RS256") +print(token) +``` + +Then send: + +```bash +curl -X POST http://localhost:8080/auth/backchannel-logout \ + -d "logout_token=${token}" \ + -H "Content-Type: application/x-www-form-urlencoded" +``` + +Expect `200 OK`. + +--- + +## Troubleshooting + +### 1. "OIDC_TOKEN_ENCRYPTION_KEY is not set" + +**Error**: Application refuses to start when `AUTH_MODE=oidc`. + +**Solution**: Generate and set the key: +```bash +python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())" +export OIDC_TOKEN_ENCRYPTION_KEY= +``` + +### 2. "Issuer mismatch" at discovery + +**Error**: Backend logs show `Issuer mismatch: configured '…', got '…'` and `/auth/login` returns 500 "OIDC discovery failed". + +**Cause**: OpenRag enforces **byte-for-byte equality** between `OIDC_ENDPOINT`, the `issuer` field returned by the IdP's discovery document, and the `iss` claim in tokens — per OIDC Core §2. The most common culprit is a **trailing slash mismatch**: + +| IdP | Typical issuer form | +|-----|---------------------| +| Keycloak | `https://kc.example.com/realms/myrealm` (no trailing slash) | +| LemonLDAP::NG | `https://llng.example.com/` (WITH trailing slash) | +| Auth0 | `https://tenant.auth0.com/` (WITH trailing slash) | +| Google | `https://accounts.google.com` (no trailing slash) | + +**Solution**: Configure `OIDC_ENDPOINT` to match the IdP's advertised issuer **exactly**. To check what the IdP actually returns: + +```bash +curl -s http://your-idp/.well-known/openid-configuration | jq -r .issuer +``` + +Copy that string verbatim (including or excluding the trailing `/`) into `.env`: + +``` +OIDC_ENDPOINT= +``` + +OpenRag builds the discovery URL by stripping any trailing slash internally, so both forms work for discovery — but the subsequent token-claim validation is strict. + +### 3. "Invalid redirect URI" + +**Error**: IdP rejects the callback with "Invalid redirect URI" or similar. + +**Solution**: +- Ensure `OIDC_REDIRECT_URI` matches exactly what's configured in the IdP (case-sensitive, trailing slashes matter) +- Example: `https://openrag.example.com/auth/callback` (NOT `https://openrag.example.com/auth/callback/`) +- Keycloak: **Clients** → **Valid redirect URIs** + +### 4. "email claim not found" + +**Error**: User logs in successfully, but OpenRag responds with 403 "email not found in claims". + +**Solution**: +- Set `OIDC_EMAIL_SOURCE=userinfo` if `email` is not in the ID token +- Or, ask IdP admin to include `email` scope in the token +- Verify the IdP is returning `email` claim via OIDC `/userinfo` endpoint: +```bash +curl -H "Authorization: Bearer " \ + https://idp.example.com/realms/openrag/protocol/openid-connect/userinfo +``` + +### 5. "external_user_id mismatch" + +**Error**: User with `external_user_id=A` tries to log in, but OIDC `sub=B`. + +**Cause**: The user's `external_user_id` was set to one value, but the IdP's `sub` claim changed (e.g., user was re-imported or IdP was reconfigured). + +**Solution**: +- If intentional (user switched IdPs), clear the old `external_user_id`: +```bash +curl -X PATCH http://localhost:8080/users/42 \ + -H "Authorization: Bearer ${AUTH_TOKEN}" \ + -H "Content-Type: application/json" \ + -d '{"external_user_id": null}' +``` +- Then log in again; the new `sub` will be backfilled + +### 6. "email domain not whitelisted" + +**Error**: User logs in, but OpenRag responds with 403 "email domain not whitelisted". + +**Solution**: +- Set `OIDC_ALLOWED_EMAIL_DOMAINS` to allow the user's domain: +```bash +export OIDC_ALLOWED_EMAIL_DOMAINS=example.com,partner.org +``` +- Or, empty it to allow any domain + +### 6. "session not found" or "session expired" + +**Error**: User can log in once, but subsequent requests show "unauthenticated". + +**Cause**: Session cookie was lost or expired. + +**Solution**: +- Ensure cookies are enabled in browser +- Check `openrag_session` cookie exists and is not marked `revoked_at` in DB +- Increase `access_token_expires_at` via OIDC scopes (`offline_access` + longer TTL in IdP) + +### 7. "clock skew" or "token not yet valid" + +**Error**: "iat claim is in the future" or "exp claim is in the past". + +**Solution**: +- Sync system clocks between OpenRag and IdP servers +- Check NTP is running: `ntpq -p` + +### 8. "invalid scope: offline_access" + +**Error**: OIDC client redirect fails with "Invalid scope requested: offline_access". + +**Solution**: +- Keycloak: Ensure `offline_access` scope is mapped to the client + - **Clients** → `openrag` → **Client scopes** → Verify `offline_access` is in the assigned scopes +- LemonLDAP::NG: Check the OIDC relying party configuration includes `offline_access` + +--- + +## Security Considerations + +### Cookie Security + +- **httpOnly**: Cookies are marked `httpOnly`, preventing JavaScript access (XSS mitigation) +- **Secure**: In production (HTTPS), cookies are marked `Secure` (only sent over HTTPS) +- **SameSite=Lax**: CSRF protection; allows top-level navigation but not cross-site subresource requests +- **Path=/**: Cookies sent for all paths +- **No Domain**: Host-only (not shared with subdomains) + +### Token Encryption at Rest + +- Access tokens and refresh tokens are encrypted using **Fernet** (symmetric encryption) before storage in the database +- The key (`OIDC_TOKEN_ENCRYPTION_KEY`) must be kept secret +- If the key is compromised, regenerate it and re-encrypt all sessions (manual process in v1; planned for v2) + +### Token Rotation + +- Access tokens have a short expiry (typically 5-15 minutes) +- Refresh tokens have a longer expiry (typically hours or days, configured in IdP) +- Middleware automatically refreshes access tokens when <60 seconds remain before expiry (lazy refresh) +- No extra API calls for users; happens transparently + +### CSRF Mitigation + +- Authorization requests use a server-generated `state` parameter +- The `state` is stored in a temporary, signed cookie (`idp_state`, 5-minute TTL) +- The callback validates that the returned `state` matches the cookie +- Prevents CSRF attacks on the callback endpoint + +### Replay Protection + +- **PKCE** (Proof Key for Code Exchange): + - Client generates a `code_verifier` (43-128 character random string) + - Client computes `code_challenge = BASE64URL(SHA256(code_verifier))` + - Client sends `code_challenge` in the authorization request + - Callback sends `code_verifier` in the token exchange request + - IdP verifies they match, preventing authorization code interception +- **Nonce**: + - Client generates a random `nonce` + - Included in the authorization request and returned in the ID token + - Callback verifies the nonce matches, preventing token replay + +### Breach Scenarios + +| Breach | Impact | Mitigation | +|--------|--------|-----------| +| OIDC_TOKEN_ENCRYPTION_KEY leaked | All encrypted tokens (access, refresh) decryptable | Rotate key + re-encrypt sessions (v2 feature) | +| Authorization code intercepted | Code is single-use + PKCE prevents exchange without code_verifier | PKCE enforced | +| Session cookie stolen (XSS) | Attacker can impersonate user in browser | httpOnly prevents JavaScript access;

Matching is now purely by external_user_id == sub (admin MUST pre-provision with the right sub). The users.email column stays as optional metadata; it is no longer used for matching. Introduce an opt-in OIDC_CLAIM_MAPPING env var to let the IdP be the source of truth for display_name / email: OIDC_CLAIM_MAPPING=display_name:name,email:email OIDC_CLAIM_SOURCE=id_token # or 'userinfo' After a successful login, claims are read from the ID token (cheap) or /userinfo (complete) and the user row is updated.

Most issues fall into one of three categories: + +1. **Issuer mismatch** (Step 2 — trailing slash). +2. **Invalid redirect URI** (Step 1 — must match byte-for-byte). +3. **User not registered** (Step 5 — `external_user_id` ≠ `sub`). + +--- + +## Appendix — Programmatic access in SSO mode + +Once `AUTH_MODE=oidc`, human users go through SSO. **CI pipelines, scripts, and external agents** keep working by using the per-user bearer token (`users.token`) — the same one returned at `POST /users/` creation. Example: + +```bash +# The token printed when you created alice in Step 5: +curl -H "Authorization: Bearer or-xxxxxxxxxxxxxxxx" https://rag.mycorp.com/v1/models +``` + +This gives you the best of both worlds: human-friendly SSO for the UI, token-based auth for automation. From 95ec4c88aa40d6cd30c291e060f8c0c54227ce20 Mon Sep 17 00:00:00 2001 From: Yadd Date: Fri, 17 Apr 2026 13:48:03 +0200 Subject: [PATCH 07/10] fix(tests): force kid on JWKS key + add SSO quick-start doc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - JWKS kid was set with setdefault() which authlib's JsonWebKey.generate_key() had already populated with a random value, so signed JWTs advertised kid="test-key-1" while the JWKS served random-kid keys → authlib raised "Key not found" during verification. Use explicit []= assignment in all three test files (test_oidc_client.py, test_auth_router.py, test_oidc_lifecycle.py) to force the expected kid. Doc: - Add docs/sso-quickstart.md — step-by-step onboarding for non-experts: what to ask the SSO admin (client registration fields, redirect URIs, back-channel logout URL), how to verify the exact issuer string via curl | jq, how to generate the Fernet key, the .env block, and how to pre-provision users. --- openrag/components/auth/test_oidc_client.py | 4 ++-- openrag/routers/test_auth_router.py | 4 ++-- tests/api_tests/test_oidc_lifecycle.py | 4 ++-- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/openrag/components/auth/test_oidc_client.py b/openrag/components/auth/test_oidc_client.py index 9d05e011e..8a2e79198 100644 --- a/openrag/components/auth/test_oidc_client.py +++ b/openrag/components/auth/test_oidc_client.py @@ -32,8 +32,8 @@ def _make_rsa_key_pair(): _RSA_PRIVATE, _RSA_PRIVATE_JWK, _RSA_PUBLIC_JWK = _make_rsa_key_pair() _RSA_PUBLIC_JWK["use"] = "sig" _RSA_PUBLIC_JWK["alg"] = "RS256" -_RSA_PUBLIC_JWK.setdefault("kid", "test-key-1") -_RSA_PRIVATE_JWK.setdefault("kid", "test-key-1") +_RSA_PUBLIC_JWK["kid"] = "test-key-1" +_RSA_PRIVATE_JWK["kid"] = "test-key-1" JWKS_RESPONSE = {"keys": [_RSA_PUBLIC_JWK]} diff --git a/openrag/routers/test_auth_router.py b/openrag/routers/test_auth_router.py index 17de02ffa..2290efc89 100644 --- a/openrag/routers/test_auth_router.py +++ b/openrag/routers/test_auth_router.py @@ -64,8 +64,8 @@ def _make_rsa_key_pair(): _RSA_PRIVATE, _RSA_PRIVATE_JWK, _RSA_PUBLIC_JWK = _make_rsa_key_pair() _RSA_PUBLIC_JWK["use"] = "sig" _RSA_PUBLIC_JWK["alg"] = "RS256" -_RSA_PUBLIC_JWK.setdefault("kid", "test-key-1") -_RSA_PRIVATE_JWK.setdefault("kid", "test-key-1") +_RSA_PUBLIC_JWK["kid"] = "test-key-1" +_RSA_PRIVATE_JWK["kid"] = "test-key-1" JWKS_RESPONSE = {"keys": [_RSA_PUBLIC_JWK]} diff --git a/tests/api_tests/test_oidc_lifecycle.py b/tests/api_tests/test_oidc_lifecycle.py index d56f5f9dc..d89150898 100644 --- a/tests/api_tests/test_oidc_lifecycle.py +++ b/tests/api_tests/test_oidc_lifecycle.py @@ -62,11 +62,11 @@ _RSA_PRIVATE = JsonWebKey.generate_key("RSA", 2048, is_private=True) _RSA_PRIVATE_JWK = _RSA_PRIVATE.as_dict(is_private=True) -_RSA_PRIVATE_JWK.setdefault("kid", "test-key-1") +_RSA_PRIVATE_JWK["kid"] = "test-key-1" _RSA_PUBLIC_JWK = _RSA_PRIVATE.as_dict() _RSA_PUBLIC_JWK["use"] = "sig" _RSA_PUBLIC_JWK["alg"] = "RS256" -_RSA_PUBLIC_JWK.setdefault("kid", "test-key-1") +_RSA_PUBLIC_JWK["kid"] = "test-key-1" JWKS_RESPONSE = {"keys": [_RSA_PUBLIC_JWK]} From b52ad4bb03719ffb30492e3421b613b92cba9624 Mon Sep 17 00:00:00 2001 From: Yadd Date: Fri, 17 Apr 2026 13:54:55 +0200 Subject: [PATCH 08/10] refactor(auth): no default for OIDC_POST_LOGOUT_REDIRECT_URI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously defaulted to '/' which lands the user back on OpenRag's root and immediately re-triggers OIDC login (silent re-auth if the IdP session survived, or a loop if it didn't).
