## 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

## NEXT STEPS

1. **Manual Testing**: Test LDAP login with actual LDAP credentials to verify fix works end-to-end
2. **Test Local Login**: Ensure local user login still works correctly
3. **Version Bump**: Run `python3 scripts/save_version.py` if changes are validated
