Tableau Online Single Sign-On using DNN as SAML IDP

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.

• You have finished with the Installation of the module on your DNN site.

1. Configure Tableau Online as SP

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

• There are two options in the module to share your IDP metadata to the service provider. Either you can share metadata URL or you can download the metadata (XML) file.


Note: Tableau Online does not accept manual input of metadata, so directly download the XML file.

• 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 plugin, or directly download the metadata by clicking on Export metadata and later upload it in the configuration of the DNN IDP plugin.



• Upload the DNN 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 plugin as well. You can get the certificate from Tableau Metadata.

2. Configure DNN as SAML IDP

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

A] Upload metadata using Upload SP Metadata option

• IDP module requires SP Entity ID and ACS URL values from your service provider. You may get the metadata file (.xml) or metadata URL.
• You can upload metadata using Upload SP Metadata option where you can upload metadata using XML file or URL.
• You may refer to the screenshot below:

• You can choose any one of the options according to the metadata format you have available.

B] Configure the Service Provider metadata manually



• Enter the values corresponding to the information from Tableau Online. Refer to the table below.

Service Provider Name	Tableau Online
SP Entity ID or Issuer	Copy and paste the Tableau Online Entity ID from Tableau Online.
ACS URL	Copy and paste the ACS URL from Tableau Online.
NameID Format	urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
Response Signed	Unchecked
Assertion Signed	Checked
Encryption Assertion	Unchecked

• Once configured service provider metadata, Update the module settings

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 or 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 saving the attribute mapping, proceed further with the test configuration or perform actual SSO from your service provider.

4. Testing SSO

• In the Incognito browser window, enter the Tableau Online URL.
• The browser will redirect you to the DNN Login screen.
• Enter the DNN Credentials and click on Log in.
• If you are redirected back to your Tableau Online start page and logged in successfully, then your configuration is correct.

You have successfully configured DNN as SAML IDP ( Identity Provider) for achieving DNN SSO login into your Tableau Online.

You can configure the DNN SAML IDP module with any service provider such as Azure AD, Azure B2C, Google Apps, Zoho Desk, Salesforce, WordPress, Cognito, Moodle, Zapier, Zoho, Zoom, Tableau Server, Hubspot, TalentLMS, WSO2 or even with your own custom service providers. You can find more service providers here.
