|------|------|------|---------|
| Authorization Flow | `default-provider-authorization-implicit-consent` | UUID | Token generation for all grant types |
| Invalidation Flow | `default-provider-invalidation-flow` | UUID | Token revocation/logout |
---
## Grant Type Matrix
| Grant Type | Use Case | Providers | Example |
|------------|----------|-----------|---------|
| **authorization_code** | Browser login + redirect | All 6 | User clicks "Login with Authentik" |
| **implicit** | SPA/JavaScript apps | All 6 | Frontend JavaScript fetching token |
| **password** | CLI login | All 6 | `core auth login` device code |
| **client_credentials** | Service-to-service | All 6 | temporal-worker-agent → API gateway |

Authentik Admin Console
→ Providers (6)
→ Applications (6)
→ api-gw → api-gw provider
→ minio → minio provider
→ poimen → poimen provider
→ paperless → paperless provider
→ grafana → grafana provider
→ queue → queue provider (NEW)
```
**Public Endpoint**: `https://authentik.riotpiao.com/application/o/token/`

## Testing Credentials
**Test User**: `rock`
**Test Email**: `[email protected]`
**Test Group**: `homelab-admins`
**Test JWT Claims**:
```json
{
"sub": "rock",
"groups": ["homelab-admins"],
"roles": ["*"],
"permissions": ["*"],
"minio_buckets": ["*"],
"memory_projects": ["*"],
"authorized_models": ["*"],
"sqs_queues": ["*"],
"grafana_org_role": "Admin"
}
```
---
## Troubleshooting
### Issue: "Invalid client_secret"
**Solution**: Regenerate secret in Authentik UI
```bash
# Or via API
AUTHENTIK_BOOTSTRAP_TOKEN=... python3 scripts/iam/provision-rbac.py
```
### Issue: Token validation fails at gateway
**Solution**: Verify JWT claim in Authorization header
```bash
# Decode token
core auth token | jq -R 'split(".")[1] | @base64d | fromjson'
```
### Issue: X-Forwarded-User not reaching backend
**Solution**: Check api-gateway proxy configuration
```bash
kubectl logs -n api svc/api-gateway | grep "X-Forwarded"
```
### Issue: Queue provider returns 404
**Solution**: Management service API endpoints not finalized yet
```bash
# Expected in Phase 2:
# POST /api/v1/messages
# GET /api/v1/topics
```
---
## Commands for Verification
```bash
# List all OAuth2 providers
curl -s -H "Authorization: Bearer $AUTHENTIK_BOOTSTRAP_TOKEN" \
https://authentik.riotpiao.com/api/v3/providers/oauth2/ | jq '.results | length'
# Get specific provider
curl -s -H "Authorization: Bearer $AUTHENTIK_BOOTSTRAP_TOKEN" \
https://authentik.riotpiao.com/api/v3/providers/oauth2/13/ | jq '{name, client_id, grant_types}'
# Get all applications
curl -s -H "Authorization: Bearer $AUTHENTIK_BOOTSTRAP_TOKEN" \
https://authentik.riotpiao.com/api/v3/core/applications/ | jq '.results | length'
# Test client_credentials flow
curl -X POST https://authentik.riotpiao.com/application/o/token/ \
-d "grant_type=client_credentials" \
-d "client_id=queue-sqs" \
-d "client_secret=$AUTHENTIK_PROVIDER_QUEUE_SECRET" \
-d "scope=openid"
