-- Links an existing user account in a user pool (@DestinationUser@) to an
-- identity from an external IdP (@SourceUser@) based on a specified
-- attribute name and value from the external IdP. This allows you to
-- create a link from the existing user account to an external federated
-- user identity that has not yet been used to sign in. You can then use
-- the federated user identity to sign in as the existing user account.
--
-- For example, if there is an existing user with a username and password,
-- this API links that user to a federated user identity. When the user
-- signs in with a federated user identity, they sign in as the existing
-- user account.
--
-- The maximum number of federated identities linked to a user is five.
--
-- Because this API allows a user with an external federated identity to
-- sign in as an existing user in the user pool, it is critical that it
-- only be used with external IdPs and provider attributes that have been
-- trusted by the application owner.
--
-- This action is administrative and requires developer credentials.
