# Unified Identity Architecture Design
|
|
|
|
**Date**: 2025-01-27
|
|
**Purpose**: Design document for unified identity system
|
|
**Status**: Design Document
|
|
|
|
---
|
|
|
|
## Executive Summary
|
|
|
|
This document outlines the design for a unified identity system that provides single sign-on (SSO) and centralized user management across all workspace projects.
|
|
|
|
---
|
|
|
|
## Architecture Overview
|
|
|
|
### Components
|
|
|
|
1. **Identity Provider** (Keycloak, Auth0, or Entra ID)
|
|
2. **Authentication Service** (Custom or provider)
|
|
3. **User Management Service** (Centralized)
|
|
4. **Authorization Service** (RBAC/ABAC)
|
|
5. **Session Management** (JWT tokens, refresh tokens)
|
|
|
|

|
|
|
|
## Technology Options
|
|
|
|
### Option 1: Keycloak (Recommended - Self-Hosted)
|
|
|
|
**Pros**:
|
|
- Open-source and free
|
|
- Feature-rich
|
|
- Standards-compliant (OAuth2, OIDC, SAML)
|
|
- Self-hosted control
|
|
|
|
**Cons**:
|
|
- Requires infrastructure
|
|
- More setup complexity
|
|
|
|
### Option 2: Auth0
|
|
|
|
**Pros**:
|
|
- Managed service
|
|
- Easy setup
|
|
- Good documentation
|
|
- Enterprise features
|
|
|
|
**Cons**:
|
|
- Commercial (paid)
|
|
- Vendor lock-in
|
|
|
|
### Option 3: Microsoft Entra ID
|
|
|
|
**Pros**:
|
|
- Enterprise integration
|
|
- Azure ecosystem
|
|
- Good security features
|
|
|
|
**Cons**:
|
|
- Azure dependency
|
|
- Commercial (paid)
|
|
|
|
**Recommendation**: Keycloak for self-hosted, Auth0 for managed.

## Features
|
|
|
|
### Authentication
|
|
- Single Sign-On (SSO)
|
|
- Multi-factor authentication (MFA)
|
|
- Social login (Google, GitHub, etc.)
|
|
- Passwordless authentication
|
|
|
|
### Authorization
|
|
- Role-Based Access Control (RBAC)
|
|
- Attribute-Based Access Control (ABAC)
|
|
- Fine-grained permissions
|
|
- Resource-level access control
|
|
|
|
### User Management
|
|
- Centralized user directory
|
|
- User provisioning
|
|
- Profile management
|
|
- Account lifecycle
|
|

## Implementation Plan
|
|
|
|
### Phase 1: Identity Provider Setup (Weeks 1-2)
|
|
- [ ] Deploy Keycloak or configure Auth0
|
|
- [ ] Set up realms/clients
|
|
- [ ] Configure authentication flows
|
|
- [ ] Set up MFA
|
|
|
|
### Phase 2: User Management (Weeks 3-4)
|
|
- [ ] Create user management service
|
|
- [ ] Implement user provisioning
|
|
- [ ] Set up user directory
|
|
- [ ] Configure user sync
|
|
|
|
### Phase 3: SSO Implementation (Weeks 5-6)
|
|
- [ ] Implement SSO in projects
|
|
- [ ] Configure OAuth2/OIDC
|
|
- [ ] Test SSO flow
|
|
- [ ] Migrate existing users
|
|
|
|
### Phase 4: Authorization (Weeks 7-8)
|
|
- [ ] Implement RBAC
|
|
- [ ] Configure permissions
|
|
- [ ] Set up policy engine
|
|
- [ ] Test authorization
|

## Security Considerations
|
|
|
|
### Authentication Security
|
|
- Strong password policies
|
|
- MFA enforcement
|
|
- Session management
|
|
- Token security
|
|
|
|
### Authorization Security
|
|
- Principle of least privilege
|
|
- Regular access reviews
|
|
- Audit logging
|
|
- Permission validation
|
|

|
## Migration Strategy
|
|
|
|
### User Migration
|
|
1. Export users from existing systems
|
|
2. Import to unified system
|
|
3. Map existing roles/permissions
|
|
4. Test authentication
|
|
5. Cutover users
|
|
|
|
### Application Migration
|
|
1. Add SSO support
|
|
2. Test authentication flow
|
|
3. Migrate users gradually
|
|
4. Deprecate old auth
|
|
5. Complete migration
|

## Monitoring
|
|
|
|
### Metrics
|
|

|
|
- Token refresh rates
|
|
- Permission check performance
|
|
|
|
### Alerts

|
- SSO failures
|
|
- Token expiration issues
|
|
- Permission errors
