When configuring SSO for a single Procore instance, you should NOT check this box.
If your company licenses more than one Procore instance, and you want to configure unique Procore enterprise applications within your IdP tenant for each instance, you can by enabling Unique Entity ID. If enabled, you are still limited to one (1) enterprise application per Procore company instance.
Important: SSO for Procore targets users by email domain. An email domain can only be targeted once in all of Procore, so if you're considering setting up SSO with Unique Entity IDs across multiple Procore instances, remember that you can only target an email domain once, in a single instance.
To generate a Unique Entity ID for an enterprise application, check the Enable Unique Entity ID box in the Procore Admin tool's SSO configuration page for the Procore instance you want to specify on an enterprise application. Checking this box will generate a unique Entity ID URL in the field below, which you will then copy and paste into the appropriate Entity ID field in your IdP's configuration page.
Notes: You must save your configuration with the box checked to generate the Unique Entity ID. Enabling this feature does not impact user membership or access to a given instance. Access to a company in Procore is determined by a user's presence in the Directory tool, and their configured permissions within Procore. Auto-provisioning with SSO is not supported at this time.
