sourceUser

construct an aws.sdk.kotlin.services.cognitoidentityprovider.model.ProviderUserIdentifierType inside the given block

An external IdP account for a user who doesn't exist yet in the user pool. This user must be a federated user (for example, a SAML or Facebook user), not another native user.

If the SourceUser is using a federated social IdP, such as Facebook, Google, or Login with Amazon, you must set the ProviderAttributeName to Cognito_Subject. For social IdPs, the ProviderName will be Facebook, Google, or LoginWithAmazon, and Amazon Cognito will automatically parse the Facebook, Google, and Login with Amazon tokens for id, sub, and user_id, respectively. The ProviderAttributeValue for the user must be the same value as the id, sub, or user_id value found in the social IdP token.

For OIDC, the ProviderAttributeName can be any value that matches a claim in the ID token, or that your app retrieves from the userInfo endpoint. You must map the claim to a user pool attribute in your IdP configuration, and set the user pool attribute name as the value of ProviderAttributeName in your AdminLinkProviderForUser request.

For SAML, the ProviderAttributeName can be any value that matches a claim in the SAML assertion. To link SAML users based on the subject of the SAML assertion, map the subject to a claim through the SAML IdP and set that claim name as the value of ProviderAttributeName in your AdminLinkProviderForUser request.

For both OIDC and SAML users, when you set ProviderAttributeName to Cognito_Subject, Amazon Cognito will automatically parse the default unique identifier found in the subject from the IdP token.
