Provision Users and Groups with SCIM

Overview

With Instance Manager 2.3 or later, you can provision, update, or deprovision users and user groups using SCIM 2.0. SCIM, short for “System for Cross-domain Identity Management” is an open API for managing identities.

Access SCIM APIs

Instance Manager enforces RBAC for the SCIM APIs through the USER-MANAGEMENT feature. To have full access, users must be assigned to a role with Create, Read, Update, and Delete permissions.

See Also:

A feature is a grouping of functionality in Instance Manager. A role definition is a collection of permissions for one or more features.

For more information about features and roles, see the Set Up RBAC topic.

  }
}

    }
  ],
  "externalId": "idpuser@mydomain.ctrl",

    "resourceType": "User"
  },
  "name": {
    "familyName": "Example",
    "givenName": "SSO"
  },
  "schemas": [
    "urn:ietf:params:scim:schemas:core:2.0:User"
  ],
  "userName": "idpuser@mydomain.ctrl"
}

Create Group

To create a group, send a POST request similar to the following example to the /api/scim/v2/Groups endpoint:

Request

In this request, User is assigned as a member.

{
  "schemas": [
    "urn:ietf:params:scim:schemas:core:2.0:Group"
  ],
  "displayName": "Example Group",
  "externalId": "7fcb12f4-af71-4f7d-a987-6c1a91cb838a",
  "members": [
    {
      "type": "User",
      "value": "dc898740-4e9c-41a4-912c-1f3a20edf66e"
    }
  ]
}

Response 

{
  "displayName": "Example Group",
  "externalId": "7fcb12f4-af71-4f7d-a987-6c1a91cb838a",
  "id": "e023964d-8a63-44f8-aa85-51ffa6aaa8f1",
  "members": [
    {
      "type": "User",
      "value": "dc898740-4e9c-41a4-912c-1f3a20edf66e"
    }
  ],
  "meta": {
    "created": "2022-06-17T21:06:46.774Z",
    "lastModified": "2022-06-17T21:06:46.774Z",
    "location": "/api/scim/v2/Groups/e023964d-8a63-44f8-aa85-51ffa6aaa8f1",
    "resourceType": "Group"
  },
  "schemas": [
    "urn:ietf:params:scim:schemas:core:2.0:Group"
  ]
}
Important:
After creating a group with SCIM, you need to assign roles to the group in Instance Manager so the group has permissions associated with it.

Update Users Created with SCIM

To update users created with SCIM, you need to use the SCIM API or update the users directly in your identity provider (IdP). You can’t use the F5 NGINX Manager web interface to edit user details from an identity provider.
