⚙️ Configuration

Configuration File Structure

Create ad-config/ad-config.json:

{
  "ldap_server": "ldap://dc.yourdomain.com",
  "ldap_port": 389,
  "use_ssl": false,
  "base_dn": "DC=yourdomain,DC=com",
  "bind_user": "CN=MCPService,CN=Users,DC=yourdomain,DC=com",
  "bind_password": "YourSecurePassword123!",
  "default_user_ou": "OU=Users,DC=yourdomain,DC=com",
  "default_group_ou": "OU=Groups,DC=yourdomain,DC=com",
  "default_computer_ou": "OU=Computers,DC=yourdomain,DC=com",
  "auth_token": "your_secure_bearer_token_here"
}

Configuration Parameters

Parameter	Description	Required	Default
`ldap_server`	LDAP server URL (ldap:// or ldaps://)	✅ Yes	-
`ldap_port`	LDAP port (389 or 636 for SSL)	✅ Yes	389
`use_ssl`	Use LDAPS (recommended for production)	❌ No	false
`base_dn`	Base Distinguished Name for domain	✅ Yes	-
`bind_user`	Service account DN	✅ Yes	-
`bind_password`	Service account password	✅ Yes	-
`default_user_ou`	Default OU for user creation	❌ No	CN=Users
`default_group_ou`	Default OU for group creation	❌ No	CN=Users
`default_computer_ou`	Default OU for computer creation	❌ No	CN=Computers
`auth_token`	Bearer token for MCP authentication	✅ Yes	-

SSL/TLS Configuration (Production)

For production deployments, use LDAPS:

{
  "ldap_server": "ldaps://dc.yourdomain.com",
  "ldap_port": 636,
  "use_ssl": true,
  "validate_cert": true,
  "ca_cert_path": "/path/to/ca-certificate.pem"
}

Service Account Permissions

The service account (bind_user) requires these Active Directory permissions:

Read Operations (Minimum):

✅ Read all properties - on Domain root
✅ List contents - on Domain root

Write Operations (If needed):

✅ Create/Delete User objects - on Users OU
✅ Create/Delete Group objects - on Groups OU
✅ Create/Delete Computer objects - on Computers OU
✅ Reset Password - on Users OU
✅ Write all properties - on specific OUs

Security Best Practices:

Create a dedicated service account (e.g., MCPService)
Grant minimum permissions required for your use case
Use LDAPS in production
Rotate bind_password and auth_token regularly
Restrict network access to MCP server

🏢 Multi-Client Management

Adding New Clients

Use the included script to add new AD domains in minutes:

# Syntax: ./scripts/install-client.sh <slug> <name> <port>
cd /opt/mcp-servers/active-directory

# Example: Add ACME Corporation on port 8853
./scripts/install-client.sh acme-corp "ACME Corporation" 8853

What the script does:

Creates client directory structure: acme-corp/ad-config/
Generates configuration template: ad-config.json
Creates PM2 process configuration
Registers new MCP instance on specified port

Port Allocation Strategy

Standard port allocation for multi-client deployments:

Client	Port	Process Name
Client 1	8850	mcp-ad-client1
Client 2	8851	mcp-ad-client2
Client 3	8852	mcp-ad-client3
Client N	8850+N	mcp-ad-clientN

Configuration Isolation

Each client has completely isolated:

✅ AD credentials (bind_user, bind_password)
✅ Authentication tokens (auth_token)
✅ LDAP connection settings
✅ Default OUs for object creation

Process Management (PM2)

# List all MCP AD instances
pm2 list | grep mcp-ad

# View logs for specific client
pm2 logs mcp-ad-client1

# Restart specific client
pm2 restart mcp-ad-client1

# Restart all AD MCP instances
pm2 restart all

Updating Shared Codebase

When updating .base-code/, all clients automatically use the new code:

cd .base-code/
git pull origin main

# Restart all instances to apply updates
pm2 restart all

🔐 Security

Authentication

All requests require Bearer Token authentication:

Authorization: Bearer your_secure_token_here

Generate secure tokens:

# Linux/Mac
openssl rand -hex 32

# PowerShell
[Convert]::ToBase64String((1..32 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 }))

Security Best Practices

✅ Use LDAPS in production - Encrypt LDAP traffic (port 636) ✅ Rotate credentials - Change auth_token and bind_password quarterly ✅ Minimum permissions - Service account should have least privilege ✅ Network restrictions - Firewall MCP server to allowed IPs only ✅ Audit logging - Enable detailed logging for compliance ✅ Secret management - Use environment variables or secrets manager

Audit Logging

All operations are logged with:

⏰ Timestamp
👤 Authenticated user/token
🎯 Operation performed (tool name + parameters)
✅ Result (success/failure)
🌐 Source IP address

View logs:

# Docker deployment
docker-compose logs -f skills-mcp-ad

# Python deployment
tail -f logs/mcp-ad.log

🧪 Testing

Health Check

# Test server health and LDAP connectivity
curl http://localhost:8850/health \
  -H "Authorization: Bearer your_token_here"

Expected response:

{
  "status": "healthy",
  "ldap_connected": true,
  "domain": "yourdomain.com",
  "base_dn": "DC=yourdomain,DC=com",
  "timestamp": "2025-12-09T10:00:00.000Z",
  "tools_count": 45
}

Test MCP Protocol

# List available tools
curl -X POST http://localhost:8850/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your_token_here" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/list",
    "id": 1
  }'

Test User Listing

# List domain users
curl -X POST http://localhost:8850/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your_token_here" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "params": {
      "name": "list_users",
      "arguments": {
        "max_results": 10
      }
    },
    "id": 2
  }'

🔧 Troubleshooting

Common Issues

Problem	Cause	Solution
`Connection refused`	Server not running	Check Docker: `docker-compose ps` or Python process
`401 Unauthorized`	Invalid token	Verify `auth_token` in config matches request header
`LDAP bind failed`	Invalid AD credentials	Check `bind_user` and `bind_password` in config
`LDAP server unreachable`	Network/firewall	Test connectivity: `telnet dc.domain.com 389`
`Insufficient permissions`	Service account lacks rights	Grant required AD permissions to `bind_user`
`SSL certificate error`	Invalid/self-signed cert	Set `validate_cert: false` or provide valid CA cert

Debug Mode

Enable detailed LDAP operation logging:

Docker:

# docker-compose.yml
environment:
  - LOG_LEVEL=DEBUG

Python:

export LOG_LEVEL=DEBUG
python -m src.server_http

Verify LDAP Connectivity

# Test LDAP bind from command line
ldapsearch -H ldap://dc.domain.com:389 \
  -D "CN=MCPService,CN=Users,DC=domain,DC=com" \
  -W \
  -b "DC=domain,DC=com" \
  "(objectClass=domain)"

Check Port Availability

# Linux/Mac
lsof -i :8850

# Windows
netstat -an | findstr :8850
