# Story 1.4b: Authentication Integration Testing

## Status
Ready

## Story
**As a** development team,  
**I want** to validate the authentication implementation with comprehensive integration testing,  
**so that** we have confidence the authentication system works end-to-end in all scenarios.

## Dependencies
- Story 1.4: Basic Authentication Setup (Complete)

## Acceptance Criteria
1. Keycloak realm and clients are automatically configured without manual intervention
2. Complete authentication flow works from Blazor UI through Keycloak to API

## Dev Notes

### Issues Identified from Story 1.4
1. **Keycloak Realm Import Failures**
   ```
   ERROR: Unable to find composite realm role: uma_authorization
   Referenced client scope 'roles' doesn't exist
   Referenced client scope 'web-origins' doesn't exist
   ```

2. **Missing Configuration Files**
   - No `.env.example` file despite story mentioning environment variables
   - Manual setup steps not documented

3. **Package Version Conflicts**
   - Multiple Microsoft.IdentityModel package version warnings
   - Test project has version conflicts (6.35.0 vs 7.0.3)

4. **Untested Integration Points**
   - JWT token flow from Blazor to API never validated
   - Logout functionality not tested end-to-end
   - Error scenarios not covered

### Testing Environment Requirements
- Clean Docker environment for reliable testing
- Test user accounts in Keycloak
- Isolated test database
- Network connectivity for container-to-container communication

### Success Criteria
- All authentication flows work without manual intervention
- Automated tests validate critical scenarios
- Production deployment documentation complete
- No package version conflicts or build warnings
- Performance meets acceptable thresholds

## Acceptance Testing
To verify successful completion:
1. Fresh `docker-compose up` starts all services successfully
2. Keycloak realm and clients are automatically configured
3. Login flow works: Blazor → Keycloak → back to Blazor with user context
4. API calls include JWT tokens and validate successfully
5. Logout clears all sessions and returns to login
6. Automated tests pass in CI/CD pipeline
7. Production deployment checklist complete

## Security Considerations
- Validate all authentication flows for security best practices
- Ensure no sensitive information is logged
- Verify proper token expiration and refresh
- Confirm secure defaults for production deployment
- Test authentication bypass scenarios
