To authenticate using an External Identity Provider, follow these steps:
  1. Enter your email on the ABBYY Vantage page. After this, you will be redirected to the login page of the Identity Provider.
  2. Enter your login and password for the External Identity Provider. After this, you will be redirected back to Vantage.
Note: If the user’s email is registered in several tenants that are configured for authentication by the same provider, the user is prompted to choose which tenant to authenticate to.

Authentication Workflow When Using SAML Assertions

The SAML 2.0 standard ensures secure communications between the service provider and the External Identity Provider. ABBYY Vantage uses SAML assertions to exchange authentication data when interacting with a SAML 2.0 External Identity Provider. The following steps describe the authentication process when using SAML assertions:
  1. The user initiates access to Vantage.
  2. Vantage generates a SAML assertion and transfers it to the External Identity Provider (typically using POST or GET requests), while simultaneously redirecting the user to the External Identity Provider page.
  3. The user undergoes authentication with the External Identity Provider.
  4. The External Identity Provider generates the signed assertion and token.
  5. The signed assertion and token are forwarded to Vantage through POST or GET requests. If successful, Vantage establishes a session.
After that, the user can request additional resources from Vantage without having to authenticate with the External Identity Provider for every request.
