# OpenCloud OIDC Authentication Troubleshooting

## Issue Summary
OpenCloud deployment configured for Pocket ID (external OIDC) authentication, but the web frontend continues to serve a page instead of redirecting to OIDC provider.

## All Configuration Changes Applied

### 1. Deployment Environment Variables (`caf32a3`, `64ec709`)
```yaml
# OIDC Configuration
OC_OIDC_ISSUER: "https://auth.basicstack.de"
OC_OIDC_CLIENT_ID: (from opencloud-oidc-secret)
OC_OIDC_CLIENT_SECRET: (from opencloud-oidc-secret)
OC_OIDC_CLIENT_SCOPES: "openid profile email groups offline_access"
OC_JWT_SECRET: (from opencloud-jwt-secret) ✓ Added per user suggestion

# Proxy OIDC
PROXY_OIDC_REWRITE_WELLKNOWN: "true"
PROXY_USER_OIDC_CLAIM: "email"
PROXY_ENABLE_BASIC_AUTH: "false"

# Web Service OIDC
WEB_OIDC_CLIENT_ID: (from opencloud-oidc-secret)
WEB_OIDC_AUTHORITY: "https://auth.basicstack.de"
WEB_OIDC_METADATA_URL: "https://auth.basicstack.de/.well-known/openid-configuration"
WEB_OIDC_RESPONSE_TYPE: "code"
WEB_OIDC_SCOPE: "openid profile email groups offline_access"

# Disable Demo Users
IDM_CREATE_DEMO_USERS: "false"
```

### 2. ConfigMap Changes (`169cd31`, `c993aaf`, `4c89d5d`)

**Proxy Service:**
```yaml
proxy:
  oidc:
    issuer: https://auth.basicstack.de
    insecure: false
    auto_provision_accounts: true  # ✓ Enables auto-provisioning
    user_oidc_claim: email
    role_assignment:
      driver: oidc
      oidc_role_mapper:
        role_claim: groups
        role_mapping:
          - role_name: admin
            claim_value: opencloudAdmin
          - role_name: spaceadmin
            claim_value: opencloudSpaceAdmin
          - role_name: user
            claim_value: opencloudUser
          - role_name: guest
            claim_value: opencloudGuest
  enable_basic_auth: false  # ✓ Disabled
```

**Service Architecture:**
- IDP (Identity Provider) = EXCLUDED (Pocket ID handles authentication)
- IDM (Identity Management) = KEPT (provides LDAP storage for auto-provisioned users)
- `OC_EXCLUDE_RUN_SERVICES: "search,idp"`

**User/Group Storage:**
```yaml
users:
  drivers:
    ldap:  # Connected to internal IDM LDAP
      bind_password: ${OC_USERS_LDAP_BIND_PASSWORD}

groups:
  drivers:
    ldap:  # Connected to internal IDM LDAP
      bind_password: ${OC_GROUPS_LDAP_BIND_PASSWORD}
```

### 3. Removed Local User Creation (`56d9063`)
- Removed `--admin-password` flag from `opencloud init`
- Command now: `opencloud init --insecure=true --force-overwrite` (no local admin)
- `IDM_CREATE_DEMO_USERS=false`

## Verified Working

- ✓ IDM service running (LDAP listener on 127.0.0.1:9236)
- ✓ OIDC config present in `/config.json`:
  ```json
  {
    "metadata_url": "https://auth.basicstack.de/.well-known/openid-configuration",
    "authority": "https://auth.basicstack.de",
    "client_id": "2f3c0cea-697f-4dbc-9573-6f6e8adfd4b0",
    "response_type": "code",
    "scope": "openid profile email groups offline_access"
  }
  ```
- ✓ Pocket ID accessible (https://auth.basicstack.de/.well-known/openid-configuration returns 200)
- ✓ OpenCloud pod healthy and running
- ✓ No errors in logs
- ✓ `oidc-client-ts` module loaded by frontend

## Current Behavior

When accessing https://opencloud.basicstack.de:
1. Frontend HTML loads successfully (HTTP 200)
2. `/config.json` loads with OIDC configuration
3. `/themes/opencloud/theme.json` loads
4. `oidc-client-ts` JavaScript module loads
5. **But: No redirect to Pocket ID occurs**
6. Page serves content instead of redirecting

Log evidence shows normal page serving:
- `GET / → 200`
- `GET /config.json → 200`
- `GET /app/list → 200`
- Warning: "core access token not set" (normal for unauthenticated)

## Expected Behavior

With OIDC configured and no local users:
1. Frontend loads
2. JavaScript detects OIDC config
3. JavaScript detects no local auth available
4. **Automatic redirect to: `https://auth.basicstack.de/authorize?...`**
5. User authenticates with Pocket ID
6. Redirect back to OpenCloud with auth code
7. Token exchange and user auto-provisioning

## Possible Causes

### 1. Frontend Logic Issue
The OpenCloud web SPA may have additional logic that prevents OIDC-only mode:
- Checks for local user availability before deciding to redirect
- Requires a specific config option we haven't found
- Has a bug in OIDC-only detection logic

### 2. Missing Configuration
Possible undocumented configuration options:
- Web service option to disable password login UI
- Proxy option to force OIDC redirect
- ConfigMap option to set "OIDC-only mode"

### 3. Version-Specific Issue
OpenCloud v7.2.0 may have:
- Incomplete OIDC-only support
- Bug in auto-redirect logic
- Regression from earlier versions

## Next Steps for Investigation

### 1. Check OpenCloud Source Code
Examine the web frontend (SPA) source to understand:
- How it decides to redirect to OIDC vs show login form
- What configuration flags control this behavior
- Whether there's a "force OIDC" option

### 2. Test with curl/API
Try to trigger OIDC flow manually:
```bash
# Try to initiate OIDC flow
curl -i "https://opencloud.basicstack.de/signin-oidc"

# Try to access protected resource
curl -i "https://opencloud.basicstack.de/app/list"
```

### 3. Check OpenCloud Community
- Search OpenCloud GitHub issues for OIDC-only configuration
- Check OpenCloud documentation for OIDC-only examples
- Ask in OpenCloud community channels

### 4. Try Alternative Approach
Consider if OpenCloud requires a different architecture:
- Keep IDP running but configure it to proxy to Pocket ID
- Use a different authentication flow
- Check if web service needs additional OIDC configuration

### 5. Browser Developer Tools
Have user check browser console for JavaScript errors:
- Press F12 to open dev tools
- Check Console tab for errors
- Check Network tab for failed API calls
- Check if OIDC client initialization fails
