The review

What to look for

Defensive study and review of artifacts supplied by their owner. Record missing evidence as an open question.

  1. Map ownership

    Bind each provider, invitation, group mapping, and lifecycle event to a specific organization owner and approved administrator.

  2. Constrain role changes

    Require explicit policy for role assignment, deprovisioning, and cross-organization moves; do not infer authority from profile edits.

  3. Review durable links

    Validate that directory attributes and external identities retain provenance and cannot silently rebind an account.

  4. Verify revocation

    Confirm disabled users, removed memberships, and revoked providers lose access across all active interfaces.

What to produce

  • Provisioning authority map
  • Role-change policy
  • Deprovisioning verification notes

Common mistakes

  • Treating an invite as blanket authority
  • Allowing ownerless configuration
  • Leaving stale group access after deprovisioning

Visual models

The identity provider authenticates a subject and binds issued claims to it. The relying application validates the issuer, audience, signature, and ownership binding before mapping to a local account. Failed validation is rejected.An identity claim must belong to the user ↗A verified workload identity and a requested operation enter an independent authorization decision. Policy checks the role, action, resource and tenant together. Only the approved resource scope is allowed; other requests are denied. Both decisions produce an audit record.Keep workload authority tenant-scoped ↗
