Set up an IdP as usual, edit the IdP to configure it as an authoritative IdP, and then specify which population should contain the provisioned users:

  1. Set up an external identity provider if you haven’t already.

    Learn more in External IDPs.

  2. Go to Integrations > External IDPs.
  3. Locate the IdP that you want to edit.
  4. Click the Details icon to expand the IdP, and then click the Pencil icon.
  5. Click the Registration tab.
  6. In the Population section, select the population to which you want to provision users.

    Selecting a population enables just-in-time (JIT) provisioning for the configured IdP and overrides the population set in the authentication policy under Enable registration.

  7. Click Save.
