• ✅ Connects to existing AD infrastructure
• ✅ SSL/TLS security
• ✅ Resource limits & health checks
• ✅ Production logging

For development with included test LDAP server:

# 1. Start test environment
docker compose -f docker-compose-ad.yml up -d

# 2. Test the setup
python test_ad_environment.py

# 3. Access services
# - ActiveDirectoryMCP: http://localhost:8813/activedirectory-mcp
# - LDAP Admin: http://localhost:8080

Test Features:

• ✅ Includes OpenLDAP test server
• ✅ Pre-configured test data
• ✅ Web-based LDAP management
• ✅ No external AD required

For testing and development with stdio transport:

# Start stdio server
./start_server.sh

# Or with custom config
AD_MCP_CONFIG="ad-config/ad-config.json" python -m active_directory_mcp.server

For local HTTP transport development:

# Start HTTP server
./start_http_server.sh

# Or with custom settings
python -m active_directory_mcp.server_http --host 0.0.0.0 --port 8813 --path /activedirectory-mcp

• LDAP3 Compatibility: Fixed TLS configuration compatibility with latest ldap3 library
• Test Suite: All 43 tests now passing successfully (100% success rate)
• Mock Issues: Resolved integration test mocking for error scenarios
• Security Config: Removed deprecated LDAP parameters for better compatibility

1. LDAP Connection Failed

   # Test connectivity
   ldapsearch -H ldap://dc.example.com -D "CN=user,DC=example,DC=com" -W -b "DC=example,DC=com" "(objectClass=domain)"

2. Permission Denied

   • Verify service account permissions
   • Check OU access rights
   • Ensure proper LDAP bind DN

3. SSL/TLS Issues

   # Test SSL connection
   openssl s_client -connect dc.example.com:636 -showcerts

4. Port Already in Use

   # Check port usage
   netstat -tlnp | grep 8813
   # Change port if needed
   HTTP_PORT=8814 ./start_http_server.sh

5. ⚠️ LLM Tool Limit Warning

   Some LLM models may experience issues with 40+ tools in context.
