# CURRENT AI WORKING SESSION — HANDOVER
**Active AI:** Claude (Haiku 4.5)
**Last Updated:** 2026-04-26
**Current Version:** v1.15.0
**Status**: ✅ LDAP LOGIN BUG FIXED | 🔧 FRONTEND/BACKEND RESPONSE SYNC
---
## 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:
```json
{
"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
