Overview

Single sign-on concerns interactive user identity federation. It should not be treated as a substitute for API authorization or machine-principal lifecycle management.

Key concepts

Map an external identity to an internal user using a verified issuer and stable subject identifier. Domain membership alone is not a sufficient organization assignment.

Implementation considerations

No SSO setup is available here, and this documentation does not claim deployment of an enterprise identity provider.

Illustrative data model

This local fixture shows a possible representation for the concepts above. It is not an endpoint response, production configuration or a claim that the described capability is implemented.

{
  "reference_only": true,
  "topic": "Single Sign-On",
  "issuer": "https://identity.remizen.example",
  "subject": "subject example",
  "user_id": "usr_example_123",
  "organization_id": "org_example_123"
}

Design review checklist

Document which organization owns the single sign-on representation and which actor may view or change it.
Test the boundaries of issuer, subject, user id, organization id using synthetic values, including missing or inconsistent references.
Before future implementation, obtain an approved contract and review failure behavior. This documentation does not authorize production activation.

Proposed data types

Illustrative field dictionary

subject	string	Illustrative subject value; interpret it only within the proposed topic-specific model described above.
user_id	string	Stable fictional user reference; not a secret and not evidence that a resource exists.
organization_id	string	Stable fictional organization reference; not a secret and not evidence that a resource exists.
