admin-link-provider-for-user

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.

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.

Note

The maximum number of federated identities linked to a user is five.

Warning

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.

Note

Amazon Cognito evaluates Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

Options

--user-pool-id (string)

The ID of the user pool where you want to link a federated identity.

--destination-user (structure)

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.

Warning

All attributes in the DestinationUser profile must be mutable. If you have assigned the user any immutable custom attributes, the operation won’t succeed.

ProviderName -> (string)

The name of the provider, such as Facebook, Google, or Login with Amazon.

ProviderAttributeName -> (string)

The name of the provider attribute to link to, such as NameID .

ProviderAttributeValue -> (string)

The value of the provider attribute to link to, such as xxxxx_account .

Shorthand Syntax:

ProviderName=string,ProviderAttributeName=string,ProviderAttributeValue=string

JSON Syntax:

{
  "ProviderName": "string",
  "ProviderAttributeName": "string",
  "ProviderAttributeValue": "string"
}

--source-user (structure)

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 AdminLinkProviderForUser 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.

ProviderName -> (string)

The name of the provider, such as Facebook, Google, or Login with Amazon.

ProviderAttributeName -> (string)

The name of the provider attribute to link to, such as NameID .

ProviderAttributeValue -> (string)

The value of the provider attribute to link to, such as xxxxx_account .

Shorthand Syntax:

ProviderName=string,ProviderAttributeName=string,ProviderAttributeValue=string

JSON Syntax:

{
  "ProviderName": "string",
  "ProviderAttributeName": "string",
  "ProviderAttributeValue": "string"
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To link a local user to a federated user

The following admin-link-provider-for-user example links the local user diego to a user who will do federated sign-in with Google.
