Enabling Identity Provider Discovery
Note: Pivotal Platform is now part of VMware Tanzu. In v1.12 and later, Pivotal Single Sign‑On is named Single Sign‑On for VMware Tanzu Application Service.

This topic describes Identity Provider (IdP) Discovery and how to configure it for your VMware Tanzu Application Service for VMs (TAS for VMs) apps that use Single Sign‑On for VMware Tanzu Application Service.
If users with different email domains access the same TAS for VMs app, you can configure Single Sign‑On to authenticate them through different identity providers.
In this situation, IdP Discovery streamlines the login experience by automatically redirecting the user to their own IdP and shielding them from seeing the IdPs of other app users.
When a user logs in to an app, an account chooser autofills their email address from any previous login, or presents a choice if they have logged in from more than one account. Users can add or remove accounts from the account chooser.
As an example, consider an app where some users log in with
@example.com username and some with
With IdP Discovery, users with both email domains can log in from the same login page
and do not have to see or choose from a list of login options that covers all the domains.
IdP Discovery ascertains each user’s IdP from their email domain.

To enable IdP Discovery:
Enable IdP Discovery for the Single Sign‑On service instance that your app is bound to:

Enter the Email domains you want to include as a comma-separated list under the configuration page for the identity provider plan, and click Save.
In Apps Manager, navigate to your space, open the Service tab, and select your service instance.
Click the Manage link under the service name, and edit the app configuration by selecting the required Identity Providers.
After these steps, the login page prompts for the username first:
If the user enters their
@example.com username, they are redirected to the Okta login page:
