SCIM (System for Cross-domain Identity Management) integration

Reference docs

Okta integration

https://developer.okta.com/docs/guides/scim-provisioning-integration-prepare/main/

Sample provisioning settings that work. Capabilities can be disabled and attributes can be removed as needed.

From our testing with Okta, we see the following behavior that is worth noting:

Okta does not use PATCH endpoint
Okta does not DELETE users; if a new user needs to be created with the same username as a "deleted" user, then it overwrites the old user

Automated test for Okta integration

First, create at least one SCIM user:

POST https://localhost:8080/api/latest/fleet/scim/Users
Authorization: Bearer <API key>
{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
    "userName": "test.user@okta.local",
    "name": {
        "givenName": "Test",
        "familyName": "User"
    },
    "emails": [{
        "primary": true,
        "value": "test.user@okta.local",
        "type": "work"
    }],
    "active": true
}

Run test using Runscope. See instructions.

Entra ID integration

SCIM guide
SCIM validator
- Only test attributes that we implemented

Testing Entra ID integration

Use scimvalidator.microsoft.com. Only test the attributes that we have implemented.

To see our supported attributes, check the schema:

GET https://localhost:8080/api/latest/fleet/scim/Schemas

Results (2025/05/06)

Authentication

We use same authentication as API. HTTP header: Authorization: Bearer xyz
