SCIM provisioning

Zulip has beta support for user provisioning and deprovisioning via the SCIM protocol. In SCIM, a third-party SCIM Identity Provider (IdP) acts as the SCIM client, connecting to the service provider (your Zulip server).

See the SCIM help center page for documentation on SCIM in Zulip Cloud as well as detailed documentation for how to configure some SCIM IdP providers.

Synchronizing groups via SCIM is currently not supported.

Server configuration

The Zulip server-side configuration is straightforward:

1. Pick a client name for your SCIM client. This name is internal to your Zulip configuration, so the name of your IdP provider is a good choice. We'll use okta in the examples below.

2. First a SCIM client entry needs to be added to the database. Run manage.py add_scim_client <client name> -r <subdomain>. For example, if your organization is hosted on a subdomain (subdomain.zulip.example.com):

   /home/zulip/deployments/current/manage.py add_scim_client okta -r 'subdomain'
   

   Or your organization is hosted on the root domain (zulip.example.com):

   /home/zulip/deployments/current/manage.py add_scim_client okta -r ""
   

   See the management command documentation for details on how to run management commands.

3. Configure the Zulip server by adding a SCIM_CONFIG block to your /etc/zulip/settings.py:

   SCIM_CONFIG = {
        "subdomain": {
            "bearer_token": "<secret token>",
            "scim_client_name": "okta",
            "name_formatted_included": False,
        }
    }
   

   The bearer_token should contain a secure, secret token that you generate. You can use any secure password generation tools for this, such as the apg command included by default in some Linux distributions. For example, apg -m20 will generate some passwords of minimum length 20 for you.

   The SCIM IdP will authenticate its requests to your Zulip server by sending a WWW-Authenticate header like this: WWW-Authenticate: Bearer <secret token>. name_formatted_included needs to be set to False for Okta. It tells Zulip whether the IdP includes name.formatted in its User representation.

4. Now you can proceed to configuring your SCIM IdP. Use the value Bearer <secret token> using the bearer_token you've generated earlier as the API token that the SCIM IdP will ask for when configuring authentication details.
