Tableau Server Single Sign-On using DNN SAML as 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. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between DotNetNuke(DNN) and Tableau Server 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 Server 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.

• You can also manually share the IdP metadata by copying the IdP Entity ID, Single Sign-On URL, SAML SLO URL, NameID Format, and x.509 Certificate.

• Login to your Tableau Services Manager as Admin.
• In the Configuration tab, select User Identity Access, then click on Authentication Method tab.

To configure Tableau Server follow the given steps:

• In Authentication Method, select SAML and provide the data from the IDP Configurations tab of the module.

Tableau Server return URL	Enter the URL that Tableau Server users will access.
SAML Entity ID	The entity ID uniquely identifies your Tableau Server installation to the IDP. Enter the IDP Entity ID from the DNN IDP Metadata (Manual Configuration) section.
SAML certificate and key files	Copy the x.509 Certificate from the DNN IDP Metadata (Manual Configuration) section. You can paste it into a text file and save it as cert.crt. Then, upload it to Tableau Server.

• Click on Download XML Metadata File, this will be required for configuring the IDP.

• Navigate to the IDP Configurations tab of the DNN SAML IDP Module and download the IDP metadata file.
• Now, you can upload the Metadata XML File of the Identity Provider.

• Enter the assertion values that you want to map during SSO.

Username	username
Display name	displayName
Email	email

• You can check or uncheck the checkbox if you wish to enable or disable the SAML Single Logout.

• Click on Save Pending Changes and then click on Pending Changes at the top of the page.

• Click Apply Changes and Restart to restart your Tableau server.

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 Server.

There are two options to add an application for your Service Provider in the DNN SAML 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

• In the Incognito browser window, enter the Tableau Server 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 Server 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 Server.

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.
