Tableau Online Single Sign-On using DNN as SAML IDP

Overview

DotNetNuke (DNN) SAML IDP module acts as a SAML 2.0 Identity Provider which can be configured to establish the trust between the module and various SAML-compliant service providers to securely authenticate the user using the DotNetNuke (DNN) site credentials. miniOrange provides a ready to use solution for SAML 2.0 Login using DotNetNuke credentials. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between DotNetNuke(DNN) and Tableau Online considering DotNetNuke(DNN) as IDP.

Pre-requisites : Download And Installation

• Download DNN SAML Identity Provider (IDP) module.

• Upload the installation package xxx_dnn-saml-single-sign-on-sso-idp_xxx_Install by going in Settings > Extension > Install Extension.

• Open any of the page on your DNN site (Edit mode) and Click on Add Module.

• Search for moDNNSAMLIDP and click on the moDNNSAMLIDP. Drag and drop the module on the page where you want.

• After successfully installing the module on your DNN site, click the gear icon of the module, and select Settings from the dropdown menu.

• Navigate to the moDNNSAMLIDP Settings tab to configure the module.

• To activate the module, enter the license key received via email in the provided input field.
• If you haven’t received the license key, click on the Click Here link to download it, and then upload the license file using the Choose File button.

• Then, accept the terms and conditions by checking the box, and click on the Activate License button to activate the module.

Step 1: Configure Tableau Online as SP

• Navigate to the IDP Configurations tab in the DNN SAML IDP module.

• You can share your IdP Metadata with the Service Provider in either of the following ways:
  • Metadata URL : Share the metadata URL with your Service Provider.

  OR

  • Download Metadata XML : Download the metadata XML file and upload it to your Service Provider.

• Log in to your Tableau Dashboard as Admin.
• Go to Authentication Settings in the Settings menu.

• Under Authentication types, select Enable an additional authentication method and enable SAML as shown below. Click on Edit Connection.

• Note down the Tableau Entity ID and Assertion Consumer Service URL (ACS URL) which will be needed to configure the module, or directly download the metadata by clicking on Export metadata and later upload it in the configuration of the DNN SAML IDP module.

• Upload the DNN SAML IDP Metadata file in the Import metadata file section. Click on the Apply button to upload the Metadata file.

Optional: If your Tableau SP is configured to send Signed Requests then you will need to provide the certificate in the module as well. You can get the certificate from Tableau Metadata.

Step 2: Configure DNN as SAML IDP

• Navigate to the SP Configurations tab and click on the Add Application button.

• From the list of service providers given below, select Tableau Online.

There are two options to add an application for your Service Provider in the IDP module

A] Upload Metadata using the “Upload Metadata” option

• You can upload the Service Provider metadata directly using the Upload Metadata button.

• The DNN SAML IDP module requires the SP Entity ID and ACS URL values from your Service Provider.
• You may receive these values either through a metadata file (.xml) or a metadata URL from your SP.
• Upload the metadata by selecting the appropriate option — via XML file or URL — as shown in the screenshot below.

B] Configure the Service Provider metadata manually

• If you prefer to configure the Service Provider manually, copy the SP Entity ID and ACS URL from your Service Provider’s metadata and paste them into the corresponding fields.

• Once you have entered all required details, click on Save Settings to save the configuration.

Step 3: Attribute Mapping

• In this steps you will map the DotNetNuke user attribute to be sent in the response to the Service Provider.
• NameID defines what SP is expecting in the subject element of SAML Assertion. Generally, NameID is Username of Email Address. You can select which user attribute you want to send in the NameID.
• You can add other attributes to be sent in SAML Assertion to SP. The attributes include user’s profile attributes such as first name, last name, fullname, username, email, custom profile attributes etc.

• After completing the attribute mapping, click on the Save Settings button to save your configurations.

Step 4: Testing SSO

• Go back to the Import Metadata file into Tableau Online section and click on Test Connection. Upon successful connection, you will see the following message on your screen.

Step 5: IdP Initiated SSO

• Once the SSO connection is successfully tested, you can proceed to copy the DNN IdP initiated SSO link.
• After adding your Service Provider, click on Select Actions → Copy SSO Link.
  For DNN (IdP) initiated SSO, you can use the SSO link provided by the DNN SAML IDP module to directly initiate login from your DNN site.

In this Guide, you have successfully configured Tableau Online SAML Single Sign-On (Tableau Online SSO Login) choosing Tableau Online as SP and DNN as IdP. This solution ensures that you are ready to embed your Tableau charts into your DNN site.

Step 6: Embedded Views (Optional)

• After following the above steps to Single Sign On (SSO) in Tableau, select Default Authentication Type of Embedded Views to Authenticate using an inline frame from Authentication Settings.

• Go to your Tableau View and select the view you desire to show in an Iframe.

• Click on Share and click on Copy Link or on Copy Embed Code.

• Go to your DNN site, click on Add Module, and select the HTML module.

• After adding it to the page, open the module and paste your embed code inside it and click on save.
