Redirect to Adobe Identity Type from the Adobe Sign Login Page
When a user goes to the Adobe Sign login page (e.g. https://secure.adobesign.com/public/login, Image 1) and enters their email address, they are automatically routed to the Adobe identity type authentication (Image 2) to complete the sign-in process.
If the user's administrator has configured the account to authenticate with a Federated ID (i.e. SAML), they are routed to their company's corporate log-in page.
