SCIM Deep Dive

Introduction

SCIM (System for Cross-domain Identity Management) is an open standard designed to facilitate the management of user identities across different systems and applications. SCIM aims to simplify the process of user provisioning and deprovisioning while also standardizing the way user data is exchanged between identity providers and service providers.

Key Concepts

Implementation Steps

1. Define SCIM Endpoints

Set up the necessary SCIM endpoints for your application:

GET /Users
POST /Users
GET /Users/{id}
PUT /Users/{id}
DELETE /Users/{id}

2. Implement User Schema

Create a user schema that adheres to the SCIM standards. Here is a basic example:

{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
    "id": "12345",
    "userName": "jdoe",
    "name": {
        "givenName": "John",
        "familyName": "Doe"
    },
    "emails": [
        {
            "value": "jdoe@example.com",
            "primary": true
        }
    ]
}

3. Configure Authentication

Ensure that your SCIM API is secured with proper authentication mechanisms, such as OAuth 2.0.

4. Test SCIM Integration

Use tools like Postman to test your SCIM API endpoints.

Best Practices

• Use HTTPS to secure data in transit.
• Implement paging for large data sets.
• Set up logging and monitoring for your SCIM endpoints.
• Regularly review and update your user schemas to meet organizational needs.
