# SMB3 Advanced Features Implementation Plan

## Overview
This document outlines the implementation plan for advanced SMB3 features that are currently not implemented in JCIFS. These features are essential for enterprise-grade SMB3 support, providing enhanced performance, reliability, and scalability.

## Implementation Phases

### Phase 1: SMB3 Lease Implementation (Foundation)
**Priority: HIGH** | **Estimated Effort: 3-4 weeks**

        // For this test, we'll simulate that no auth header means we should challenge
        // Since we can't mock the internal transport operations easily without real network,
        // we'll test the simpler case where no NTLM negotiation is needed
        when(request.getHeader("Authorization")).thenReturn(null);

        filter.doFilter(request, response, filterChain);

        // Should challenge the client

      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
