# OIDC Role Mapping Implementation Summary
|
|
|
|
## 🎯 Project Completion Overview
|
|
|
|
This document summarizes the complete OIDC role mapping implementation for Headscale and Headplane, delivering enterprise-grade role-based access control through OIDC group claims.
|
|
|
|
## ✅ Implementation Status: COMPLETE
|
|
|
|
All planned features have been successfully implemented, tested, and documented.
|
|
|
|
## 🏗️ Architecture Implemented
|
|
|
|
### Headscale Enhancements
|
|
- **Groups Storage**: Added `groups` TEXT field to users table with JSON storage
|
|
- **OIDC Integration**: Enhanced claims processing to extract and persist groups from OIDC tokens
|
|
- **Helper Methods**: Added `GetGroups()` and `SetGroups()` methods for safe group management
|
|
- **Migration**: Database migration `202509161200` with proper rollback support
|
|
- **Automatic Updates**: Groups are refreshed on every OIDC login
|
|
|
|
### Headplane Enhancements
|
|
- **Role Mapping Engine**: Sophisticated group-to-role mapping with configurable hierarchy
|
|
- **Authentication Flow**: Enhanced OIDC callback to assign roles based on group membership
|
|
- **Database Schema**: Added `groups` JSON field to users table
|
|
- **Zero-Trust Security**: New users get `member` role with zero capabilities by default
|
|
- **Dynamic Updates**: User roles and capabilities updated on every login
|
|
|

## 🔐 Security Model Implemented
|
|
|
|
### Zero-Trust Approach
|
|
- **Default Deny**: New users get `member` role with zero capabilities
|
|
- **Explicit Allow**: Only users with recognized groups get elevated privileges
|
|
- **Dynamic Enforcement**: Role changes take effect immediately on next login
|
|
|
|
### Role Hierarchy (Highest Privilege Wins)
|
|
1. **Owner** (`owner` role) - Full system access including user management
|
|
2. **Admin** (`admin` role) - Administrative access to all features
|
|
3. **Network Admin** (`network_admin` role) - Network configuration and routing
|
|
4. **IT Admin** (`it_admin` role) - Machine and user management
|
|
5. **Auditor** (`auditor` role) - Read-only access for compliance
|
|
6. **Member** (`member` role) - Zero capabilities (no UI access)
|
|
|
|
### Group Mapping Examples
|
|
```yaml
|
|
role_mapping:
|
|
owner: ["ceo", "cto", "headscale-owner"]
|
|
admin: ["it-admin", "platform-admin", "headscale-admin"]
|
|
network_admin: ["network-team", "devops", "infrastructure"]
|
|
it_admin: ["helpdesk", "support-team", "it-staff"]
|
|
auditor: ["compliance", "audit-team", "security"]
|
|
```
|
|
|
|

## 🏆 Success Metrics
|
|
|
|
The implementation successfully addresses the original security gap where OIDC users were receiving 'member' role with zero capabilities regardless of their authorization level. Now:
|
|
|
|
- **100% Automated Role Assignment**: Users receive appropriate roles based on group membership
|
|
- **Zero Trust Security**: New users get minimal access until proper groups are verified
|
|
- **Enterprise Integration**: Seamless integration with existing identity providers
|
|
- **Production Ready**: Complete testing, documentation, and deployment procedures
|
|
|
|
This implementation transforms Headscale and Headplane from a basic VPN solution into an enterprise-grade, role-based access control system that integrates seamlessly with organizational identity management infrastructure.
