cognitoidentityprovider_admin_link_provider_for_user: Links an existing user account in a user pool...

In paws.security.identity: 'Amazon Web Services' Security, Identity, & Compliance Services

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

Description

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.

Usage

cognitoidentityprovider_admin_link_provider_for_user(
  UserPoolId,
  DestinationUser,
  SourceUser
)

Arguments

UserPoolId	[required] The ID of the user pool where you want to link a federated identity.
DestinationUser	[required] The existing user in the user pool that you want to assign to the external IdP user account. This user can be a local (Username + Password) Amazon Cognito user pools user or a federated user (for example, a SAML or Facebook user). If the user doesn't exist, Amazon Cognito generates an exception. Amazon Cognito returns this user when the new user (with the linked IdP attribute) signs in. For a native username + password user, the ProviderAttributeValue for the DestinationUser should be the username in the user pool. For a federated user, it should be the provider-specific user_id. The ProviderAttributeName of the DestinationUser is ignored. The ProviderName should be set to Cognito for users in Cognito user pools. All attributes in the DestinationUser profile must be mutable. If you have assigned the user any immutable custom attributes, the operation won't succeed.
SourceUser	[required] 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 mapped value from a claim in the ID token, or that your app retrieves from the userInfo endpoint. For SAML, the ProviderAttributeName can be any mapped value from a claim in the SAML assertion. The following additional considerations apply to SourceUser for OIDC and SAML providers. 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 admin_link_provider_for_user request. For example, email. When you set ProviderAttributeName to Cognito_Subject, Amazon Cognito will automatically parse the default unique identifier found in the subject from the IdP token.
