Overview

SAML federation exchanges signed assertions between an identity provider and a service provider. A future evaluation should consider assertion audience, recipient and replay prevention.

Key concepts

Validate trusted signatures, assertion validity windows and the intended destination. Attribute mapping must distinguish an immutable identity from a mutable email address.

Implementation considerations

The example is metadata for discussion, not a working SAML endpoint. Certificates and customer federation details must never be pasted into this documentation.

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": "SAML Authentication",
  "issuer": "https://identity.remizen.example",

}

Design review checklist

Document which organization owns the saml authentication representation and which actor may view or change it.
Test the boundaries of issuer, audience, subject, expires at 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
Name	Type	Description
issuer	string	Reserved identity-provider illustration, not a configured Remizen provider.
audience	string	Proposed intended recipient identifier to validate independently of token decoding.
subject	string	Illustrative subject value; interpret it only within the proposed topic-specific model described above.
expires_at	string (date-time)	Synthetic UTC timestamp. Business occurrence time may differ from delivery or processing time.
