- Changed user field from Optional[User] to required User type
- Ensures user object is always included in login response
- Pydantic now properly serializes the complete user object
- Frontend can now successfully retrieve response.user for localStorage
- Fix password encoding: Convert password to UTF-8 bytes for LDAP protocol compatibility
- Add 'user' field to TokenResponse schema for frontend compatibility
- Update login endpoint to populate user object in response
- Resolves 'Invalid Protocol Password' error on LDAP login attempts
The issue was that frontend expected response.user but backend only returned
individual fields (user_id, username, role), causing localStorage assignment to fail.
