Set Up Amazon Redshift IAM Identity Center OAuth

Starting in Tableau 2023.3.2 for on premise (Tableau Desktop, Tableau Server, and Tableau Prep), you can use OAuth 2.0/OIDC to federate identity from an external identity provider to Amazon Redshift. This feature is not available for OSX because of driver limitations.

Note: Due to Unicode issues on Linux, the Redshift ODBC 2.0 driver will not currently work with Linux if your identifiers (database names, table names, view names, and column names are not in English. We are waiting for an updated driver from Amazon.

These instructions are for the newer AWS IAM IDC service. For original IAM integration see Set Up Amazon Redshift IAM OAuth.

Depending on the identity provider, there are different steps needed to configure the integration. This is a high level overview. Tableau cannot provide detailed instructions for how to configure AWS or the IDP, but this is the general approach.

Configure the IDP

  1. Create OAuth clients on the IDP for Tableau Desktop and Tableau Server or Tableau Cloud. The Desktop client should enable PKCE and use http://localhost redirects.

  2. Add any required custom claims to use for authorization to roles.

  3. Create the Tableau OAuth config files. See documentation on GitHub(Link opens in a new window), and examples(Link opens in a new window). We welcome examples for other IDPs.

    1. Be sure to prefix the Tableau OAuth config IDs with “custom_”.

    2. If your IDP supports dynamic localhost port then disable OAUTH_CAP_FIXED_PORT_IN_CALLBACK_URL. If it does not, make sure to add several localhost callback URLs to the allowlist in the config file and on the IDP.

  4. Install Tableau OAuth config files on Tableau Desktop machines and Tableau Server or Tableau Cloud sites.

Step 2: Configure IDP and Roles on AWS

See your AWS documentation for information on doing this.

Step 3: Connect to Redshift

  1. Connect to Redshift.

  2. Select OAuth for Authentication.

  3. Select Identity Center for Federation Type.

  4. (Optional) Specify the Identity Center Namespace if necessary.

When correctly configured, you will be redirected to the IDP to authenticate and authorize tokens for Tableau. Tableau will receive an access token and refresh tokens. It will send the access token to the driver for authentication.


By default Redshift OAuth to IAM IDC passes the access token to the driver. For on-premise customers, including those using Tableau Bridge, you may use a TDC file to pass the ID token instead.

<connection-customization class='redshift' enabled='true' version='10.0'>
	<vendor name='redshift' />
	<driver name='redshift' />
		<customization name='CAP_OAUTH_FEDERATE_ID_TOKEN' value='yes'/>

For more information about configuring and installing .tdc files, see Customize and Tune a Connection(Link opens in a new window) and Using a .tdc File with Tableau Server(Link opens in a new window).


If you are using Okta, it's better to use a "custom authorization server" instead of the "org authorization server." The custom authorization servers are more flexible. A custom authorization server is created by default and called "default". The authorization URL should look like this:


Update the driver

For Redshift OAuth using IAM IDC service, you must use the Redshift ODBC driver starting with version, which can be downloaded from opens in a new window). Note there is no v2 driver for OSX.

Troubleshooting Redshift IAM IDC OAuth

If you see an error message about invalid/expired token coming from the driver on the first connection (it will have a SQLState error code like [28000] or [08001] in the error message), then Tableau successfully completed the OAuth flow, and failed in the driver. This means there is a misconfiguration on either the AWS side or the IDP side. There may also be permissions or authorization errors returned from the driver, which is also out of Tableau's control.

The best way to diagnose these errors is to remove Tableau from the picture. You first need to get an access token (the default for IAM IDC) or refresh token (if customized) to send to the driver.

Here is an example with Okta. Almost all IDPs have a way to do this which is quite similar. Note that to use this flow you need to have enabled resource owner password grant type. Substitute the IDP URL, client secret, client ID, username, and password.

curl -X POST "https://OKTA_URL/v1/token" \
-H 'accept: application/json' \
-H "Authorization: Basic $(echo -n 'CLIENTID:CLIENTSECRET' | base64)" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=password&username=USER&password=PASSWORD&scope=openid"

Once you have the token, you can use a DSN to test. Below is an example of using the ODBC driver manager on Windows. On Mac you can use the iODBC driver manager UI. On Linux you can use the isql command line tool that is included with Tableau Server in the customer-bin folder.
