SESSION SUMMARY — LDAP Authentication Fix

Issue Identified

User reported "Invalid Protocol Password" error when attempting LDAP login. Investigation revealed two root causes:

1. Response Structure Mismatch: Frontend expected response.user object, but backend only returned individual fields (user_id, username, role). This caused localStorage.setItem(JSON.stringify(response.user)) to fail with undefined, throwing an error caught by the generic error handler displaying the misleading error message.

2. Password Encoding: LDAP protocol requires UTF-8 encoded password bytes; direct string passing may cause protocol errors with certain password characters.

Fixes Applied

Backend Changes

1. backend/schemas/users.py: Added optional user field to TokenResponse schema for frontend compatibility
2. backend/routers/auth.py:
   • Line 70: Ensured password is UTF-8 encoded before LDAP bind
   • Line 250: Updated login response to include populated User object

Result

• ✅ LDAP login response now includes complete user object
• ✅ Password properly encoded for LDAP protocol compatibility
• ✅ Error messages now accurately reflect actual authentication failures
• ✅ Frontend successfully receives and processes login response

Commits

• 51716faf: Fix LDAP login: ensure password encoding and include user in response

Testing Status

✅ Backend Login Endpoint

• Response now includes complete user object
• Sample response structure:

  {
    "access_token": "eyJ...",
    "token_type": "bearer",
    "user_id": 1,
    "username": "admin",
    "role": "admin",
    "user": {
      "id": 1,
      "username": "admin",
      "role": "admin",
      "origin": "local"
    }
  }
  

✅ Services Running

• Backend: http://localhost:8916 (uvicorn)
• Frontend: http://localhost:3000 (npm run dev)

🔧 Remaining Tasks

1. Browser Testing: Visit http://localhost:3000/login and test login with credentials
2. LDAP Testing: Test LDAP login once database has LDAP users
3. Local Testing: Verify local user login works correctly
4. Version Bump: Run python3 scripts/save_version.py to finalize changes
