TL;DR: Authorization systems built on authentication primitives often become fragile because they treat roles, scopes, and claims as if they fully answer access questions, according to Authzed. Relationship-based access control shifts the decision to graph-based subject-resource relationships, which makes fine-grained permissions easier to reason about and harder to encode incorrectly. When access is modeled as relationships, the governance problem becomes lifecycle and consistency, not just login integration.
Editorial analysis by NHI Mgmt Group, based on content published by Authzed: “Relationship Based Access Control (ReBAC): Using Graphs to Power your Authorization System”.
Key questions
Q: What breaks when authorization is skipped after authentication?
A: When authorization is skipped, any valid credential can become broad access.
Q: Why does relationship-based access control reduce authorization drift?
A: Because access is represented as explicit subject-resource relationships, not as overloaded identity attributes that each application interprets differently.
Q: How should IAM teams use ReBAC without losing control of access governance?
A: Use ReBAC to model who is connected to what, then place it inside a policy layer that also evaluates context, sensitivity, and lifecycle status.
Practitioner guidance
- Separate authentication facts from authorization rules Inventory where groups, scopes, and claims are being used as implicit access decisions, then remove that logic from application code where possible.
- Model permissions as relationships Define the core subject-resource links that actually represent access in your business, such as ownership, membership, editor, or delegate.
- Govern schema changes like policy changes Treat relationship schema updates as controlled changes with versioning, testing, and rollback expectations.
Bottom line: Many access systems become fragile because they treat authentication attributes as if they were complete authorization rules.

Authorization confusion is the real governance failure, not lack of identity data. The article shows that groups, scopes, and claims are often treated as if they were sufficient answers to access questions, when they are only identity facts. That assumption breaks once permission decisions need to survive application growth, delegation, and service-by-service interpretation. IAM teams should treat authorization as a separate control plane, not as an extension of authentication metadata.
A question worth separating out:
Q: What is the operational risk if different services interpret access relationships differently?
A: You get authorization drift, where the same subject can be allowed in one service and denied in another. That creates inconsistent enforcement, hard-to-diagnose access bugs, and a governance gap between policy design and what users actually experience.
