A step-by-step guide to securing a Ruby on Rails RAG (Retrieval-Augmented Generation) application using Auth0 for authentication and Auth0 FGA (Fine-Grained Authorization) for document-level access control. The tutorial covers setting up OmniAuth-based login, defining a ReBAC authorization model in Auth0 FGA, creating relationship tuples between users and documents, and filtering vector search results to only include documents the authenticated user is permitted to access — preventing sensitive data from leaking into LLM context.
