- [x] Configure Proxmox OAuth2/OpenID integration ✅
- [ ] Set up WebAuthn/FIDO2 (optional, future enhancement)
- [ ] Configure additional service integrations (n8n, Home Assistant, etc.)

**Configuration Details:**
- Container: Debian 12 LXC (2 vCPUs, 4GB RAM, 20GB disk)
- Database: PostgreSQL on 10.0.10.20 (database: authentik, user: authentik)
- Secret Key: ZsJQbVLiCRtg23rEkXPuxIDJL5MxOxdQsf8ZJ+JHB9U=
- DB Password: authentik_password_8caaff5a73f9c66b
- Version: 2025.10.2

- Admin User: akadmin
- API Token: f7AsYT6FLZEWVvmN59lC0IQZfMLdgMniVPYhVwmYAFSKHez4aGxyn4Esm86r

**Proxmox SSO Integration:**
- OAuth2 Provider: "Proxmox OpenID" (Client ID: proxmox)
- Client Secret: OAfAcjzzPDUnjEhaLVNIeNu1KR0Io06fB8kA8Np9DTgfgXcsLnN5DogrAfhk5zteazonVGcXfaESvf8viCQFVzq8wNVcp60Bo5D3xvfJ9ZjCzEMCQIljssbfr29zjsap
- Configured on all 3 Proxmox hosts:
  - main-pve (10.0.10.3) ✅
  - gaming-pve (10.0.10.2) ✅
  - backup-pve (10.0.10.4) ✅
- Scope mappings: openid, email, profile
- Login method: Click "Login with authentik" button on Proxmox login page
- Status: ✅ Working - seamless SSO authentication

**Notes:**
- Using external PostgreSQL instead of bundled container for centralized database management
- Authentik SSO successfully integrated with all Proxmox hosts
- Users authenticate once to Authentik, then access all Proxmox hosts without re-authentication
- Documentation created: AUTHENTIK-SSO-GUIDE.md and AUTHENTIK-QUICK-START.md

- [x] SSO Investigation: ❌ OIDC SSO requires n8n Enterprise license (not available in free self-hosted version)

**Notes:**
- n8n OIDC/SSO is an Enterprise-only feature
- Free self-hosted version uses standard email/password authentication
- For SSO integration, would need n8n Cloud subscription or Enterprise license
- Current deployment uses regular authentication - fully functional

### 6.4 n8n + Claude Code Integration ✅ COMPLETED
**Completion Date:** 2025-12-14
**Actual Time:** ~2 hours
**Status:** ✅ Basic integration operational, ready for production workflows

**Reference:** https://github.com/theNetworkChuck/n8n-claude-code-guide

**Architecture:**
- n8n (10.0.10.22 on main-pve) → SSH → Claude Code (10.0.10.10 on HOMELAB-COMMAND)

**Key Configuration Notes:**
- Windows SSH requires PowerShell as default shell for Claude Code to work
- SSH commands MUST use `-n` flag or "Disable Stdin" option to prevent hanging
- Claude Code headless mode: `--output-format json --permission-mode acceptEdits`
- Test workflow created and verified: "Claude Code Test"

#### 6.4.1 Install Claude Code on HOMELAB-COMMAND (10.0.10.10) ✅
- [x] SSH or RDP to HOMELAB-COMMAND (10.0.10.10)
- [x] Node.js already installed: v24.11.0
- [x] Claude Code already installed: v2.0.65
- [x] Verified installation: `claude --version`
- [x] Test headless mode: `claude -p "What is 2+2?" --output-format json --permission-mode acceptEdits`

#### 6.4.2 Configure SSH Access for n8n ✅
- [x] SSH server already running on HOMELAB-COMMAND (Windows OpenSSH)
- [x] Set PowerShell as default SSH shell (required for Claude Code):
  ```powershell
  New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force
  Restart-Service sshd
  ```
- [x] Generated SSH key on n8n VM: `ssh-keygen -t ed25519 -C "n8n-to-homelab-command"`
- [x] Added public key to HOMELAB-COMMAND: `C:\Users\Fred\.ssh\authorized_keys`
- [x] Test passwordless SSH: `ssh Fred@10.0.10.10 "hostname"` ✅
- [x] Test Claude Code via SSH: `ssh -n Fred@10.0.10.10 "claude -p 'What is 2+2?' --output-format json --permission-mode acceptEdits"` ✅
- [x] **Critical:** Must use `-n` flag with SSH to prevent stdin hanging

#### 6.4.3 Configure n8n SSH Credentials ✅
- [x] Logged into n8n web interface (http://10.0.10.22:5678)
- [x] Created SSH credential: **homelab-command-ssh**
  - **Host:** 10.0.10.10
  - **Port:** 22
  - **Username:** Fred
  - **Authentication:** Private Key (from `~/.ssh/id_ed25519` on n8n VM)
- [x] Connection tested successfully ✅
- [x] Credential saved

#### 6.4.4 Create Test Workflow ✅
- [x] Created new workflow: "Claude Code Test"
- [x] Added **Manual Trigger** node
- [x] Added **SSH** node:
  - **Credential:** homelab-command-ssh
  - **Command:** `claude -p "What is 2+2?" --output-format json --permission-mode acceptEdits`
  - **SSH Options:** Enabled "Disable Stdin" (equivalent to `-n` flag)
- [x] Added **Code** node to parse JSON response:
  ```javascript
  const sshOutput = $input.item.json.stdout;
  const claudeResponse = JSON.parse(sshOutput);
  return {
    answer: claudeResponse.result,
    cost: claudeResponse.total_cost_usd,
    duration_seconds: claudeResponse.duration_ms / 1000,
    session_id: claudeResponse.session_id
  };
  ```
- [x] Executed workflow successfully ✅
- [x] Verified Claude Code response: "2 + 2 = 4"

#### 6.4.5 Advanced: Session Management Workflow
- [ ] Add **Code** node to generate session UUID:
  ```javascript
  const uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
    const r = Math.random() * 16 | 0;
    const v = c == 'x' ? r : (r & 0x3 | 0x8);
    return v.toString(16);
  });
  return [{ json: { sessionId: uuid } }];
  ```
- [ ] Add **SSH** node for initial query:
  - **Command:** `claude -p "{{ $json.prompt }}" --session-id {{ $json.sessionId }}`
- [ ] Add **SSH** node for follow-up:
  - **Command:** `claude -r --session-id {{ $('UUID Generator').item.json.sessionId }} -p "{{ $json.followup }}"`
- [ ] Test multi-turn conversation

#### 6.4.6 Optional: Slack Integration
- [ ] Install Slack app in n8n
- [ ] Create workflow triggered by Slack messages
- [ ] Use SSH node to send message to Claude Code
- [ ] Return Claude response to Slack thread
- [ ] Implement session tracking for conversations

#### 6.4.7 Optional: Tool Deployment
For automated skill deployment (UniFi, infrastructure tasks):
- [ ] Update SSH command to include `--dangerously-skip-permissions`:
  ```bash
  claude --dangerously-skip-permissions -p "Your task requiring tools"
  ```
- [ ] Test with infrastructure directory context:
  ```bash
  cd /path/to/infrastructure && claude -p "Check WireGuard status"
  ```

#### 6.4.8 Verification & Testing ✅ BASIC TESTING COMPLETE
- [x] Test basic headless command from n8n ✅
- [ ] Test session-based multi-turn conversation (optional - future enhancement)
- [x] Verify Claude Code can access local files on HOMELAB-COMMAND ✅
- [ ] Test error handling (network disconnect, invalid commands) (optional - future enhancement)
- [ ] Monitor resource usage on HOMELAB-COMMAND during heavy Claude operations (ongoing)
- [x] Document SSH requirements: Must use `-n` flag or "Disable Stdin" option in n8n

#### 6.4.9 Production Considerations
- [ ] Set appropriate SSH timeout in n8n (default may be too short for complex Claude tasks)
- [ ] Configure Claude Code project context on HOMELAB-COMMAND:
  - Clone infrastructure repo to known location
  - Set up CLAUDE.md in project directory
- [ ] Consider output length limits (Slack: 4000 chars, n8n processing limits)
- [ ] Set up logging for Claude Code executions
- [ ] Add error notifications to n8n workflow
- [ ] Optional: Add Pangolin route for public n8n access (with Authentik SSO)
