+```
+
+## 🔧 Component Design
+
+### 1. Apache Guacamole Daemon (guacd)
+**Role**: Protocol handling and connection management
+
+```dockerfile
+# Lightweight guacd container
+FROM guacamole/guacd:latest
+EXPOSE 4822
+# Custom configuration for Headplane integration
+COPY guacd.conf /etc/guacamole/
+```
+
+**Configuration**:
+- **SSH connections**: Direct to Tailscale nodes
+- **Connection pooling**: Efficient resource usage
+- **Protocol support**: SSH, RDP, VNC as needed
+- **Security**: Connection isolation and timeout handling
+
+### 2. Python ASGI Backend
+**Role**: WebSocket bridge and authentication/authorization
+
+```python
+# Core FastAPI application
+from fastapi import FastAPI, WebSocket, Depends
+from fastapi.security import HTTPBearer
+import asyncio
+import websockets
+
+app = FastAPI()
+
+class GuacamoleProxy:
+    def __init__(self):
+        self.guacd_host = "guacd"
+        self.guacd_port = 4822
+    
+    async def create_connection(self, protocol: str, params: dict):
+        """Create guacamole connection with protocol-specific params"""
+        pass
+    
+    async def stream_session(self, websocket: WebSocket, connection_id: str):
+        """Proxy guacamole protocol over WebSocket"""
+        pass
+
+@app.websocket("/terminal/{node_name}")
+async def terminal_endpoint(
+    websocket: WebSocket, 
+    node_name: str,
+    user: User = Depends(get_current_user)
+):
+    # Check role-based permissions
+    permissions = get_terminal_permissions(user.groups)
+    if not permissions['ssh']:
+        await websocket.close(4003, "Insufficient permissions")
+        return
+    
+    # Create guacamole connection
+    proxy = GuacamoleProxy()
+    connection = await proxy.create_connection("ssh", {
+        "hostname": node_name,
+        "username": user.preferred_username,
+        "port": "22"
+    })
+    
+    # Stream session
+    await proxy.stream_session(websocket, connection.id)
+```
+
+**Key Features**:
+- **Authentication**: Validate user sessions from Headplane
+- **Authorization**: Role-based access control using OIDC groups
+- **WebSocket proxy**: Bridge between SPA and guacd protocol
+- **Session management**: Track active connections and resources
+- **Audit logging**: Record all connection attempts and activities
+
+### 3. Custom SPA Frontend
+**Role**: User interface and terminal rendering
+
+```typescript
+// Terminal component using xterm.js
+import { Terminal } from 'xterm';
+import { FitAddon } from 'xterm-addon-fit';
+import { WebLinksAddon } from 'xterm-addon-web-links';
+
+class GuacamoleTerminal {
+  private terminal: Terminal;
+  private socket: WebSocket;
+  
+  constructor(private nodeHostname: string) {
+    this.terminal = new Terminal({
+      theme: { background: '#1a1a1a' },
+      fontSize: 14,
+      fontFamily: 'JetBrains Mono, monospace'
+    });
+    
+    this.terminal.loadAddon(new FitAddon());
+    this.terminal.loadAddon(new WebLinksAddon());
+  }
+  
+  async connect() {
+    const wsUrl = `wss://${location.host}/api/terminal/${this.nodeHostname}`;
+    this.socket = new WebSocket(wsUrl);
+    
+    this.socket.onmessage = (event) => {
+      this.terminal.write(event.data);
+    };
+    
+    this.terminal.onData((data) => {
+      this.socket.send(data);
+    });
+  }
+}
+```
+
+**UI Features**:
+- **Modern terminal**: xterm.js with full VT100 compatibility
+- **Responsive design**: Works on desktop, tablet, mobile
+- **File transfer**: Drag-and-drop file uploads via SFTP
+- **Session tabs**: Multiple concurrent connections
+- **Role indicators**: Clear display of user permissions
+
+## 🔐 OIDC Role Integration
+
+### Permission Matrix
+Integration with existing OIDC role mapping system:
+
+```python
+def get_terminal_permissions(user_groups: list[str]) -> dict:
+    """Get terminal access permissions based on OIDC groups"""
+    role = map_oidc_groups_to_role(user_groups)  # Use existing mapping
+    
+    permissions = {
+        'owner': {
+            'ssh': True,
+            'rdp': True, 
+            'vnc': True,
+            'file_transfer': True,
+            'session_recording': False,  # Owners don't need to be recorded
+            'connection_sharing': True,
+            'admin_nodes': True
+        },
+        'admin': {
+            'ssh': True,
+            'rdp': True,
+            'vnc': True, 
+            'file_transfer': True,
+            'session_recording': True,   # Record admin sessions
+            'connection_sharing': True,
+            'admin_nodes': True
+        },
+        'network_admin': {
+            'ssh': True,
+            'rdp': False,
+            'vnc': False,
+            'file_transfer': True,
+            'session_recording': True,
+            'connection_sharing': False,
+            'admin_nodes': False  # Only access to regular nodes
+        },
+        'it_admin': {
+            'ssh': True,
+            'rdp': True,   # IT needs RDP for Windows support
+            'vnc': False,
+            'file_transfer': True,
+            'session_recording': True,
+            'connection_sharing': False,
+            'admin_nodes': False
+        },
+        'auditor': {
+            'ssh': False,  # Read-only access
+            'rdp': False,
+            'vnc': False,
+            'file_transfer': False,
+            'session_recording': False,
+            'connection_sharing': False,
+            'admin_nodes': False,
+            'view_sessions': True,     # Can view active sessions
+            'replay_sessions': True    # Can replay recorded sessions
+        },
+        'member': {
+            'ssh': False,
+            'rdp': False,
+            'vnc': False,
+            'file_transfer': False,
+            'session_recording': False,
+            'connection_sharing': False,
+            'admin_nodes': False
+        }
+    }
+    
+    return permissions.get(role, permissions['member'])
+```
+
+### Environment Variable Configuration
+Extend existing environment variable system for remote access:
+
+```bash
+# Existing OIDC role mapping
+HEADPLANE_ADMIN_GROUPS="vp,director,manager"
+HEADPLANE_NETWORK_ADMIN_GROUPS="devops,network,sre"
+
+# New remote access permissions
+HEADPLANE_SSH_ALLOWED_GROUPS="admin,network_admin,it_admin"
+HEADPLANE_RDP_ALLOWED_GROUPS="admin,it_admin" 
+HEADPLANE_SESSION_RECORDING_REQUIRED="admin,network_admin,it_admin"
+HEADPLANE_FILE_TRANSFER_ALLOWED="admin,network_admin,it_admin"
+```
+
+## 🚀 Deployment Strategy
+
+### Docker Compose Setup
+```yaml
+services:
+  headplane:
+    # Existing Headplane service
+    environment:
+      - HEADPLANE_REMOTE_ACCESS_ENABLED=true
+      - HEADPLANE_GUACD_HOST=guacd
+  
+  guacd:
+    image: guacamole/guacd:latest
+    container_name: headplane-guacd
+    restart: unless-stopped
+    volumes:
+      - ./guacd.conf:/etc/guacamole/guacd.conf:ro
+    expose:
+      - "4822"
+  
+  remote-access-backend:
+    build: ./remote-access
+    container_name: headplane-remote-access
+    restart: unless-stopped
+    environment:
+      - GUACD_HOST=guacd
+      - GUACD_PORT=4822
+      - HEADPLANE_API_URL=http://headplane:3000
+    expose:
+      - "8000"
+    depends_on:
+      - guacd
+      - headplane
+```
+
+### Integration Points
+- **Authentication**: Validate JWT tokens from Headplane

+# 🚀 OIDC Improvements Summary
+
+## Overview
+This document summarizes the comprehensive OIDC authentication and role mapping improvements implemented for Headplane. These changes transform OIDC configuration from complex and error-prone to intelligent and self-configuring.
+
+## 🎯 Key Improvements
+
+### 1. Convention Over Configuration Role Mapping
+- **Smart pattern recognition**: Automatically maps common group names to appropriate roles
+- **Case-insensitive matching**: Works with any capitalization (CEO, ceo, Ceo)
+- **Role hierarchy**: Highest privilege role wins when users have multiple groups
+- **Provider compatibility**: Works with Google Workspace, Azure AD, Keycloak, Okta patterns
+
+**Example Mappings:**
+```
+ceo, founder, executives     → owner
+admin, administrator, managers → admin  
+devops, network, sre         → network_admin
+helpdesk, support, it        → it_admin
+auditor, compliance, security → auditor
+unknown-group               → member
+```
+
+### 2. Environment Variable Configuration
+- **Override system**: Environment variables take precedence over conventions
+- **Easy customization**: Perfect for enterprise deployments
+- **Comma-separated format**: Simple configuration syntax
+- **Fallback gracefully**: Unmapped groups fall back to intelligent pattern matching
+
+**Configuration Examples:**
+```bash
+HEADPLANE_ADMIN_GROUPS="vp,director,manager"
+HEADPLANE_OWNER_GROUPS="ceo,cto,founders"  
+HEADPLANE_NETWORK_ADMIN_GROUPS="devops,network,sre"
+HEADPLANE_IT_ADMIN_GROUPS="helpdesk,support,it"
+HEADPLANE_AUDITOR_GROUPS="audit,compliance,security"
+```
+
+### 3. Configuration Self-Healing
+- **Auto-scope detection**: Automatically adds "groups" scope for role mapping
+- **Auto-redirect generation**: Creates redirect_uri from PUBLIC_URL or HEADPLANE_URL
+- **Provider-specific optimizations**: Different scope recommendations per identity provider
+- **Helpful guidance**: Shows environment variable setup suggestions
+
+**Auto-Enhancements Applied:**
+- ✅ Added "groups" to scope for role mapping
+- ✅ Auto-generated redirect_uri: http://localhost:3000/admin/oidc/callback
+- ✅ Provider-specific insights and configuration tips
+- ✅ Environment variable guidance for easier setup
+
+### 4. Provider-Specific Intelligence
+Smart configuration adjustments based on identity provider:
+
+**Google Workspace:**
+- Detects accounts.google.com issuer
+- Provides admin console configuration guidance
+- Recommends email-based group mapping
+
+**Azure AD:**
+- Detects login.microsoftonline.com issuer  
+- Adds groups scope automatically
+- Warns about required API permissions
+
+**Keycloak:**
+- Detects keycloak in issuer URL
+- Adds both groups and roles scopes
+- Provides client mapper configuration tips
+
+**Okta:**
+- Detects okta.com issuer
+- Optimizes scope for groups claim
+- Provides authorization server setup guidance
+
+## 📁 Files Modified

+- **Enterprise integration**: Works with existing identity infrastructure
+
+### For Developers
+- **Maintainable code**: Clean separation of concerns
+- **Comprehensive testing**: Full test coverage for production confidence
+- **Extensible design**: Easy to add new providers or role patterns
+
+## 🔄 Migration Path
+
+### Existing Deployments
+- **Backward compatible**: No breaking changes to existing configurations
+- **Automatic migration**: Old user database automatically migrated to SQL
+- **Graceful fallbacks**: Errors provide helpful guidance
+
+### New Deployments
+- **Minimal configuration**: Only issuer, client_id, and client_secret required
+- **Auto-enhancement**: Scope and redirect_uri generated automatically
+- **Provider guidance**: Specific setup instructions per identity provider
+
+## 🚀 Future Integration Opportunities
+
+### Remote Access Control
+The role mapping system is designed to integrate with planned remote access features:
+
+```python
+# Example integration with guacamole-based remote access
+def get_terminal_permissions(user_groups: list[str]) -> dict:
+    role = map_oidc_groups_to_role(user_groups)
+    
+    return {
+        'owner': {'ssh': True, 'rdp': True, 'vnc': True, 'session_recording': False},

+# 🗑️ WASM SSH Console Removal
+
+## Summary
+The 38MB WASM SSH console has been identified as problematic for VPN infrastructure and removed from the codebase.
+
+## Issues with WASM SSH Approach
+
+### Security Concerns
+- **38MB attack surface**: Massive binary running in browser with full WASM capabilities
+- **Client-side crypto**: Private keys in browser memory/storage = major security risk
+- **Browser isolation bypass**: WASM can potentially break sandbox protections
+- **Audit nightmare**: How do you security-audit a 38MB binary blob?
+
+### Performance Issues
+- **38MB download**: Unacceptable for web applications (should be <1MB)
+- **Build complexity**: Requires Go toolchain and large dependency tree
+- **Disk space issues**: Filled up `/tmp` during compilation (31GB consumed)
+- **Poor mobile experience**: Heavy download and resource usage
+
+### Architectural Problems
+- **Wrong abstraction**: Browsers aren't meant to be SSH clients
+- **Maintenance nightmare**: Go dependencies, build pipeline complexity
+- **Supply chain risk**: Massive dependency tree with Tailscale components
+
+## Actions Taken
+
+### Immediate Cleanup
+- ✅ Removed `app/hp_ssh.wasm` (38MB file)
+- ✅ Documented security and performance concerns
+- ✅ Created migration path to guacamole-based solution
+
+### Files Still Present (for reference)
+- `app/routes/ssh/console.tsx` - SSH console route (currently broken without WASM)
+- `app/routes/ssh/hp_ssh.d.ts` - TypeScript definitions
+- `cmd/hp_ssh/` - Go source code for WASM build
+- `nix/ssh-wasm.nix` - Nix build configuration
+
+## Recommended Next Steps
+
+### Short Term
+1. **Disable SSH route**: Comment out or remove SSH console route registration
+2. **Update navigation**: Remove SSH terminal links from machine management UI
+3. **Documentation**: Update README to remove WASM SSH references
+
+### Long Term - Guacamole Integration
+Implement the proposed guacamole + Python ASGI architecture:
+1. **Server-side security**: All SSH connections handled on trusted infrastructure
+2. **Lightweight frontend**: <1MB custom SPA vs 38MB WASM
+3. **Role-based access**: Integrate with existing OIDC role mapping
+4. **Enterprise features**: Session recording, audit trails, multi-protocol support
+
+## Code Changes Needed
+
+### Remove SSH Navigation
+Update `app/routes/machines/components/menu.tsx`:
+```typescript
+// Remove SSH button from machine menu
+// Lines 100-125 contain SSH button implementation
+```
+
+### Disable SSH Route
+Option 1 - Comment out route:
+```typescript
+// Temporarily disable SSH console route
+// export { default } from './ssh/console.tsx';
+```
+
+Option 2 - Add feature flag:
+```typescript
+// Add to config schema
+ssh_console_enabled: stringToBool.default(false)
+
+// Conditional route loading
+if (config.ssh_console_enabled) {
+  // Load SSH route
+}
+```
+
+## Migration Benefits
+
+Moving from WASM SSH to guacamole architecture provides:
+- **99% smaller payload**: <1MB vs 38MB
+- **Enhanced security**: Server-side connections only
+- **Better UX**: Standard web technologies, mobile-friendly
+- **Enterprise ready**: Audit trails, session recording, role-based access
+- **Maintainable**: Standard container stack vs Go/WASM complexity
+
+## Files to Update
+
+### Configuration
+- [ ] `config.example.yaml` - Remove SSH-related config if any
+- [ ] `app/server/config/schema.ts` - Add ssh_console_enabled flag
+
+### Routes & Navigation  
+- [ ] `app/routes/machines/components/menu.tsx` - Remove SSH buttons
+- [ ] `app/routes/ssh/console.tsx` - Disable or remove route
+- [ ] `app/routes/_layout.tsx` - Remove SSH navigation if present
+
+### Build System
+- [ ] `Dockerfile` - Remove WASM build steps
+- [ ] `mise.toml` - Remove WASM build task
+- [ ] `.gitignore` - Keep `app/hp_ssh.wasm` entry for safety
+
+### Documentation
+- [ ] `README.md` - Remove WASM SSH references
+- [ ] Add guacamole architecture documentation
+
+## Impact Assessment
+
+### Users
+- **Existing deployments**: SSH route will show error without WASM file
+- **New deployments**: No impact if SSH route disabled
+- **Migration path**: Clear documentation for guacamole transition
+
+### Developers
+- **Build simplification**: No more Go/WASM build complexity
+- **Dependency reduction**: Remove Tailscale build dependencies  
+- **Testing improvement**: Eliminate WASM-related test complexity
+
+### Security Teams
+- **Risk reduction**: Eliminate 38MB client-side attack surface
+- **Audit simplification**: Remove complex WASM security review requirement
+- **Compliance**: Standard web technologies easier to audit and approve
+
+## Conclusion
+
+Removing the WASM SSH console eliminates significant security, performance, and maintenance issues while paving the way for a professional guacamole-based remote access solution that better serves VPN infrastructure security requirements.

+# OIDC Authentication and Role Mapping
+
+Headplane supports authentication via external identity providers using OpenID Connect (OIDC), with automatic role assignment based on group membership. This enables enterprise-grade, role-based access control integrated with your existing identity infrastructure.
+
+## Features
+
+- **Single Sign-On (SSO)**: Seamless authentication with popular identity providers
+- **Automatic Role Assignment**: Users receive appropriate roles based on OIDC group membership
+- **Zero-Trust Security**: New users get minimal access until proper groups are assigned
+- **Dynamic Updates**: User roles update automatically on each login
+- **Configurable Mapping**: Customize which groups map to which roles for your organization
+
+## Basic Configuration
+
+### 1. Identity Provider Setup
+
+First, configure your identity provider to work with Headplane:
+
+=== "Keycloak"
+    1. Create a new client for Headplane
+    2. Set client protocol to `openid-connect`
+    3. Set access type to `confidential`
+    4. Add redirect URI: `https://your-headplane.com/admin/oidc/callback`
+    5. Configure group membership mapper (see [Group Configuration](#group-configuration))
+
+=== "Azure AD"
+    1. Create new App Registration
+    2. Add redirect URI: `https://your-headplane.com/admin/oidc/callback`
+    3. Enable ID tokens
+    4. Configure API permissions for `GroupMember.Read.All`
+    5. Add groups claim to ID tokens
+
+=== "Okta"
+    1. Create new Web Application
+    2. Add redirect URI: `https://your-headplane.com/admin/oidc/callback`
+    3. Configure group claims in token
+    4. Set grant types to Authorization Code
+
+### 2. Headplane Configuration
+
+Configure OIDC in your `config.yaml`:
+
+```yaml
+oidc:
+  # OIDC provider configuration
+  issuer: "https://your-provider.com/realm"
+  client_id: "headplane-client"
+  client_secret: "your-client-secret"
+  
+  # Include groups scope for role mapping
+  scope: "openid email profile groups"
+  
+  # Headplane callback URL
+  redirect_uri: "https://your-headplane.com/admin/oidc/callback"
+  
+  # API key for Headscale communication
+  headscale_api_key: "your-headscale-api-key"
+  
+  # Optional: Disable API key login (force OIDC only)
+  disable_api_key_login: false
+```
+
+### 3. Headscale Configuration
+
+Ensure Headscale is configured to extract and store OIDC groups:
+
+```yaml
+oidc:
+  issuer: "https://your-provider.com/realm"
+  client_id: "headscale-client"
+  client_secret: "your-client-secret"
+  scope: ["openid", "profile", "email", "groups"]  # Include groups
+```
+
+## Role Mapping
+
+### Default Role Hierarchy
+
+Headplane uses a hierarchical role system where the highest privilege group determines the final role:
+
+1. **Owner** - Full system access including user management
+2. **Admin** - Administrative access to all features
+3. **Network Admin** - Network configuration and routing
+4. **IT Admin** - Machine and user management
+5. **Auditor** - Read-only access for compliance
+6. **Member** - Zero capabilities (no UI access)
+
+### Configuring Role Mapping
+
+Add role mapping configuration to automatically assign roles based on OIDC groups:
+
+```yaml
+oidc:
+  # ... other OIDC configuration ...
+  
+  # Custom role mapping for your organization
+  role_mapping:
+    owner: ["ceo", "cto", "headplane-owners"]
+    admin: ["it-admins", "platform-team", "administrators"]
+    network_admin: ["network-team", "devops", "infrastructure"]
+    it_admin: ["helpdesk", "support-team", "it-staff"]
+    auditor: ["compliance", "audit-team", "security"]
+```
+
+### Group Matching
+
+Groups are matched using several strategies:
+
+1. **Exact Match**: Group name exactly matches mapping configuration
+2. **Case Insensitive**: `Admin`, `admin`, and `ADMIN` all match
+3. **Partial Match**: Groups containing keywords like `admin`, `network`, `audit`
+
+### Example Role Mappings by Organization Type
+
+=== "Corporate IT"
+    ```yaml
+    role_mapping:
+      owner: ["cto", "it-director"]
+      admin: ["senior-admin", "platform-lead"]
+      network_admin: ["network-ops", "infrastructure"]
+      it_admin: ["helpdesk", "desktop-support"]
+      auditor: ["compliance", "security-team"]
+    ```
+
+=== "Healthcare"
+    ```yaml
+    role_mapping:
+      owner: ["chief-information-officer"]
+      admin: ["hipaa-admin", "system-admin"]
+      network_admin: ["clinical-infrastructure"]
+      it_admin: ["medical-devices", "clinical-support"]
+      auditor: ["hipaa-compliance", "privacy-officer"]
+    ```
+
+=== "Financial Services"
+    ```yaml
+    role_mapping:
+      owner: ["compliance-officer", "risk-management"]
+      admin: ["fintech-admin", "trading-systems"]
+      network_admin: ["market-data", "trading-infrastructure"]
+      it_admin: ["client-support", "operations"]
+      auditor: ["sox-audit", "regulatory-compliance"]
+    ```
+
+## Group Configuration
+
+### Keycloak Group Setup
+
+1. **Create Groups**: Create groups in Keycloak that match your role mapping
+2. **Group Membership Mapper**:
+   - Name: `groups`
+   - Mapper Type: `Group Membership`
+   - Token Claim Name: `groups`
+   - Add to ID token: ✓
+   - Add to access token: ✓
+   - Add to userinfo: ✓
+   - Full group path: ✗ (recommended)
+
+### Azure AD Group Setup
+
+1. **Create Security Groups**: Create groups in Azure AD
+2. **Configure Group Claims**:
+   - Go to Token Configuration
+   - Add groups claim
+   - Select "Security groups"
+   - Include in ID tokens and Access tokens
+
+### Okta Group Setup
+
+1. **Create Groups**: Create groups in Okta
+2. **Configure Claims**:
+   - Go to Claims (ID Token)
+   - Add claim named `groups`
+   - Value type: Groups
+   - Filter: Matches regex `.*`
+
+## Security Model
+
+### Zero-Trust Approach
+
+- **Default Deny**: New users receive `member` role with zero capabilities
+- **Explicit Allow**: Only users with recognized groups get elevated privileges
+- **Regular Validation**: Group membership checked on every login
+- **Audit Trail**: All role assignments logged for compliance
+
+### First User Bootstrap
+
+The first OIDC user automatically receives the `owner` role regardless of group membership, ensuring administrative access is available for initial setup.
+
+### Role Capabilities
+
+| Role | Capabilities |
+|------|-------------|
+| **Owner** | Full access + user management + system configuration |
+| **Admin** | All features except owner-level user management |
+| **Network Admin** | Network configuration, DNS, routing, machine management |
+| **IT Admin** | Machine management, user support, limited network access |
+| **Auditor** | Read-only access to all features for compliance |
+| **Member** | No UI access (can only use Tailscale client) |
+
+## Advanced Configuration
+
+### Custom Profile Picture Sources
+
+Choose where profile pictures are sourced from:
+
+```yaml
+oidc:
+  # Use OIDC provider pictures (default)
+  profile_picture_source: "oidc"
+  
+  # Or use Gravatar based on email
+  profile_picture_source: "gravatar"
+```
+
+### Extra Authentication Parameters
+
+Pass additional parameters to the authorization endpoint:
+
+```yaml
+oidc:
+  extra_params:
+    prompt: "select_account"  # Force account selection
+    domain_hint: "example.com"  # Azure AD domain hint
+    acr_values: "mfa"  # Request multi-factor auth
+```
+
+### Token Endpoint Configuration
+
+Customize how tokens are exchanged:
+
+```yaml
+oidc:
+  # Method for client authentication
+  token_endpoint_auth_method: "client_secret_post"  # or "client_secret_basic"
+  
+  # Manual endpoint configuration (if discovery fails)
+  authorization_endpoint: "https://provider.com/auth"
+  token_endpoint: "https://provider.com/token"
+  userinfo_endpoint: "https://provider.com/userinfo"
+```
+
+## Monitoring and Troubleshooting
+
+### Enable Debug Logging
+
+Set environment variable for detailed OIDC logs:
+
+```bash
+HEADPLANE_DEBUG_LOG=true
+```
+
+### Common Issues
+
+**Groups not appearing in roles:**
+- Verify `groups` scope is included in OIDC configuration
+- Check identity provider group mapper configuration
+- Ensure user is member of mapped groups
+
+**Wrong role assigned:**
+- Review role mapping configuration for group name matching
+- Check for case sensitivity issues
+- Verify group hierarchy (highest privilege wins)
+
+**First login fails:**
+- Ensure redirect URI matches exactly in identity provider
+- Check client secret is correct
+- Verify Headscale API key is valid and has sufficient permissions
+
+### Validation Steps
+
+1. **Test OIDC Flow**: Use identity provider's test tools to verify token contents
+2. **Check Groups**: Verify `groups` claim appears in ID token or UserInfo response
+3. **Review Logs**: Check Headplane logs for role assignment messages
+4. **Database Check**: Verify groups are stored in Headplane user database
+
+## Migration from Manual Roles
+
+### Gradual Migration Strategy
+
+1. **Deploy with Feature Disabled**: Deploy OIDC role mapping but keep manual roles
+2. **Test with Pilot Users**: Enable role mapping for select test users
+3. **Validate Mappings**: Ensure all groups map to expected roles
+4. **Full Rollout**: Enable role mapping for all users
+5. **Cleanup**: Remove manual role assignments after validation
+
+### Backup and Rollback
+
+Before enabling OIDC role mapping:
+
+```bash
+# Backup current user roles
+sqlite3 /var/lib/headplane/headplane.db \
+  "SELECT id, sub, caps FROM users;" > user_roles_backup.sql
+
+# Rollback if needed
+sqlite3 /var/lib/headplane/headplane.db < user_roles_backup.sql
+```
+
+## Integration with Headscale
+
+Headplane's OIDC role mapping works in conjunction with Headscale's OIDC group storage:
+
+1. **Headscale** extracts groups from OIDC claims and stores them in the database
+2. **Headplane** reads groups from Headscale users and maps them to roles
+3. **Dynamic Updates** ensure role changes take effect on next login
+4. **Consistent State** between Headscale groups and Headplane roles
+
+This integration provides a complete enterprise identity solution while maintaining separation of concerns between the VPN control plane (Headscale) and management interface (Headplane).
+
