  • [ ] Keycloak ↔ PostgreSQL
  • [ ] Frontend ↔ Backend

Configuration

  • [ ] SAML configuration initialized in DB
  • [ ] Branch entities created (london, manchester, newcastle, birmingham)
  • [ ] LDAP roles created (Admin, Staff, Customers, Operators, Agents)

Environment Variables

To Add/Update: 

# SAML protocol settings
SAML_ENABLED=1
SAML_SP_ENTITY_ID=http://localhost/api/v1/auth/saml/metadata
SAML_ACS_URL=http://localhost/api/v1/auth/saml/acs
SAML_SLS_URL=http://localhost/api/v1/auth/saml/sls

# IdP settings (Keycloak)
SAML_IDP_ENTITY_ID=http://keycloak:8080/auth/realms/bank-ussd
SAML_IDP_SSO_URL=http://keycloak:8080/auth/realms/bank-ussd/protocol/saml
SAML_IDP_X509CERT=  # Will be populated during setup

# Optional: Logging
SAML_LOG_LEVEL=INFO

Phase 3: Deployment Steps

Step 1: Start Keycloak

cd deployment/

# Start Keycloak and PostgreSQL
docker-compose -f docker-compose-keycloak.yaml up -d

# Verify startup (wait 60+ seconds)
docker logs keycloak | tail -5
# Look for "Listening on http://0.0.0.0:8080"

Verification: - [ ] Keycloak container running - [ ] PostgreSQL container running - [ ] Keycloak accessible at http://localhost:8080 - [ ] Admin console accessible at http://localhost:8080/auth/admin

Step 2: Configure Backend SAML

cd backend/

# Run setup script
python setup_saml.py \
  --keycloak-url http://keycloak:8080 \
  --realm bank-ussd

# Expected output:
# ✓ SAML Configuration Setup
# ✓ SAML configuration saved to database
# ✓ Configuration verified

Verification: - [ ] Script runs without errors - [ ] IdP certificate fetched - [ ] Database config populated - [ ] All endpoints verified

Step 3: Verify SAML Metadata

# Access SAML metadata
curl http://localhost:8000/api/v1/auth/saml/metadata

# OR (if behind nginx)
curl http://localhost/api/v1/auth/saml/metadata

# Should return valid XML similar to:
# <?xml version="1.0"?>
# <EntityDescriptor xmlns="urn:oasis:names:tc:SAML:2.0:metadata" ...>

Verification: - [ ] Metadata endpoint accessible - [ ] Valid XML returned - [ ] SP EntityID correct - [ ] ACS URL correct

Step 4: Test SAML Login

# Verify backend is running
curl http://localhost:8000/api/v1/health

# Create test with one user
python test_saml_integration.py --provision-only

Via Web Browser: 1. Navigate to http://localhost:5173/login 2. Select "SAML" as login method (if UI supports) 3. Should redirect to Keycloak 4. Log in with: john.smith / password123 5. Should return to app authenticated

Verification: - [ ] Redirect to Keycloak works - [ ] Keycloak login page loads - [ ] User can enter credentials - [ ] After login, user returned to app - [ ] Session created in app

Step 5: Verify User Provisioning

# Run full test suite
python test_saml_integration.py

# Expected output:
# ✓ PASS: Entity 'london' exists
# ✓ PASS: Entity 'manchester' exists
# ✓ PASS: Role 'LDAP Admin Role' exists
# ✓ PASS: JIT provision 'SAML Test - John'
# ✓ PASS: Branch 'london' maps to entity
# Results: Passed: 15/15 (100%)

Database Verification: 

-- Check provisioned user
SELECT u.id, u.email, ue.entity_id, r.name
FROM users.users u
LEFT JOIN users.users_entity ue ON u.id = ue.user_id
LEFT JOIN users.user_roles ur ON u.id = ur.user_id
LEFT JOIN users.roles r ON ur.role_id = r.id
WHERE u.email LIKE '%bank.local%';

-- Expected: User with entity link and role

Verification: - [ ] Test suite passes ≥80% - [ ] Users created in database - [ ] Users linked to correct entities - [ ] Users assigned correct roles - [ ] SAML IdP links created

Phase 4: Integration Testing

Workflow Tests

Security Tests

  • [ ] SAML response signature validated

Database Tests

  • [ ] UserEntity links established
  • [ ] UserRole records created
  • [ ] Profile data persisted
  • [ ] Email data persisted

Edge Cases

  • [ ] Duplicate user login (should update, not create new)
  • [ ] User with multiple roles assigned correctly
  • [ ] Users from different branches linked to different entities
  • [ ] Logout correctly clears session

Phase 5: Production Readiness
