Original Pull Request: https://github.com/netbirdio/netbird/pull/5175

State: closed
Merged: No

Summary

Updates bootstrap-new-client.ps1 for v3.6 Smart Certificate Selection
Adds security improvements: Setup-Key redaction, REVOKE warning, verification docs

Changes

Smart Selection v3.6: Uses machine_cert_template_name + machine_cert_san_must_match instead of hardcoded thumbprint
REVOKE Warning: Prominent security box at script end reminding to revoke Setup-Key in Dashboard
Secret Redaction: Setup-Key shown as ****-****-****-****-XXXX (only last 4 chars visible)
Security Docs: Added in .NOTES section:
- SHA256 checksum verification instructions
- Authenticode signing instructions
- Setup-Key handling best practices

Test Evidence

Windows VM WhatIf Mode Test:

Step 1: Pre-Tunnel NTP Sync (Public NTP)
What if: Performing the operation "Configure public NTP" on target "W32Time".

Step 2: Starting NetBird Machine Service (Phase 1: Setup-Key)
What if: Performing the operation "Install and start with Setup-Key" on target "NetBirdMachine".

Step 3: Verifying DC Connectivity via Tunnel
  Testing LDAP (port 389)... [OK] OK
  Testing Kerberos (port 88)... [OK] OK
  Testing DNS (port 53)... [OK] OK
[OK] All required DC ports reachable via tunnel

Step 4: NTP Sync with Domain Controller
What if: Performing the operation "Configure DC NTP" on target "W32Time".

Step 5: Domain Join
[OK] Computer is already joined to test.local

Step 6: Machine Certificate Enrollment
What if: Performing the operation "Request machine certificate" on target "AD CS".

Step 7: Updating NetBird Config for mTLS (Phase 2 - Smart Selection)
What if: Performing the operation "Enable mTLS with Smart Selection" on target "C:\ProgramData\NetBird\config.yaml".

Step 8: Completing Bootstrap

DoD Checklist

Script mit allen 8 Schritten
DC-Connectivity Prüfung vor Join
NTP-Sync vor Join (Kerberos)
Smart Selection Config (kein Thumbprint)
Warnung: "REVOKE setup-key!"
Error-Handling für jeden Schritt
Integration Test: WhatIf Mode auf Windows VM
Keine Secrets in Logs (Setup-Key redacted)
Script-Signatur via Authenticode (dokumentiert)
Checksum-Verifikation dokumentieren

Closes #50

Summary by CodeRabbit

New Features
- Added Windows machine tunnel bootstrap with two-phase authentication (Setup-Key Phase 1, mTLS Phase 2)
- Implemented mTLS-based machine peer registration and management on dedicated port 33074
- Added automated machine certificate enrollment and renewal via Active Directory Certificate Services
- Introduced Domain Controller connectivity validation before domain join
- Added PowerShell automation for client bootstrap, lab setup, and service installation
Configuration & Infrastructure
- Enhanced server configuration with mTLS settings (port, CA certificates, issuer validation, domain mappings)
- Added git hooks for code formatting and secret detection
- Configured Dependabot for dependency updates and GitHub Actions for automated labeling and PR linting
