Steps to Configure Duo IdP

• Log in to your Duo Administration Console.

[A] Setup Duo as Identity source:

• In the given step, we will configure an Identity Source for the Duo primary Authentication in this Single Sign-On integration. You have two options here, you can either add an Active Directory or a SAML Identity Provider here. In this guide, we are configuring SAML Identity Provider for Identity Source. If you have already configured the Identity Source you may skip to step B.
• Select the Single Sign-On tab from the left menu pane and click on Add Source button. Here we will add the primary Authentication Source for the Duo Single Sign-On.

• Select Authentication Source as SAML Identity Provider and click on Add SAML Identity Provider button.

• Navigate to Configure Duo Single Sign-On section and provide the following values from your Identity Source:

Display Name	Provide the Identity Provider's name
Entity ID	Enter the Entity ID of your Identity Source.
Single Sign-On URL	Enter a Single Sign-On URL from your Identity Source
Existing Certificate	Upload the Certificate provided by your Identity Source

• Click on Save to save your configuration.
• Now navigate to Configure SAML Identity Provider section to download the XML metadata file, and provide the metadata file to the Identity Source.

• After Saving the configuration, click Go back to Single Sign-On.
• Select the Bridge Attributes tab, here you will map the user attributes received from the Identity Source which will be further used to configure Duo as SAML Identity Provider.
• There are some required Bridge Attributes, which are pre-defined and can not be changed or configured with Custom Bridge attributes.

• To configure any bridge attribute, you have to configure 2 parameters:
• Bridge Attribute Name: This will be an alias that will be further used by Duo as SAML Identity Provider.
• SAML Identity Provider Attribute: This is the attribute name, you are expecting to be received from your Identity Source. The name of the field may differ based on your application.

• After configuring all Bridge attributes, save the settings.

[B] Setup Duo as IDP

• Configure the following information from the Service Provider tab of the ASP.NET SAML Single Sign-On (SSO) module. Please refer to the below image for more information.

Entity ID	Enter the SP Entity ID from the Service Provider metadata section of the module.
Assertion Consumer Service (ACS) URL	Enter the ACS URL from the Service Provider metadata section of the module.

• Select the Applications tab from the left menu pane, then click Protect an Application.

• Search for Generic Service Provider.
• Then, select the Single Sign-On application and click on Protect button.

• Copy the Metadata Url, from the Metadata Section. This will be further used to configure the ASP.NET SAML Single Sign-On (SSO) module.

• Scroll down to the Service Provider section.

• In NameID field in the SAML Response section, select the Bridge Attribute you want to send to service provider as NameID.

• Scroll down to Map Attributes field in the SAML Response section:

• Configure the Mapping as per below guideline:
• Idp Attribute: This is the Bridge Attribute we mapped in the Single Sign-On settings. You may select the attribute as per your need.
• SAML Response Attribute: This is the name of the Attribute which will be sent in the SAML Response with the Bridge Attribute value as configured in Idp Attribute.

• Once configuration are complete, click save.

• Click on the Add new IDP button to configure a new Identity Provider.

• Under the Plugin Settings tab, select Duo as your identity provider from the list shown.

There are two ways detailed below with which you can configure your SAML Identity Provider metadata in the module.

A] Upload metadata using the Upload IDP Metadata button:

• If your identity provider has provided you with the metadata URL or metadata file (.xml format only), then you can simply configure the identity provider metadata in the module using the Upload IDP Metadata option.

• Copy metadata URL or download the metadata file to configure the same on your identity provider end.

• 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 identity provider metadata manually:

• After configuring your Identity Provider, it will provide you with IDP Entity ID, IDP Single Sign On URL and SAML X509 Certificate fields respectively.

• Click Save to save your IDP details.

• After uploading the metadata details, navigate to the Identity Provider Settings section. Hover over the Select Actions dropdown and click on Test Configuration.

• The screenshot below shows a successful test result. Please click on click here to complete the remaining SSO integration steps.

• If you are experiencing any error on the module end you'll be shown with the window similar to below.

• To troubleshoot the error you can follow the below steps:
• Under Troubleshoot tab, enable the toggle to receive the plugin logs.

• Once enabled, you will be able to retrieve plugin logs by navigating to Plugin Settings tab and clicking on Test Configuration.
• Download the log file from the Troubleshoot tab to see what went wrong.
• You can share the log file with us at aspnetsupport@xecurify.com and our team will reach out to you to resolve your issue.

• After testing the configuration, Map your application attributes with the Identity Provider (IdP) attributes.

• From the left-hand menu of the miniOrange ASP.NET SAML SSO Module, click on Attribute/Role Mapping tab as shown in the image.
• Map the required IdP attributes (such as Username, Email, Firstname, and Lastname) received in the SAML Response to their corresponding fields.

• Note: All the mapped attributes will be stored in the session so that you can access them in your application.
• Once the attributes are mapped, click Save Attribute Mapping to apply changes.

Custom Attribute Mapping

• If you want to pass additional attributes from your IdP, enter the Attribute Name and corresponding Attribute Value under Custom Attribute Mapping.
• From the Attribute Value (Claim) dropdown, select one of the claims you received in the Test Configuration results. For example: NameID.
• These claims correspond to the attributes sent by your Identity Provider (IdP).

• These claims correspond to the attributes sent by your Identity Provider (IdP).

• In the Attribute Name field, enter the name of the attribute as you want it to appear or be used in your .NET application.
• You can add multiple mappings if your application requires multiple attributes by clicking on the + button.
• After defining all the required mappings, click on Save Attribute Mapping to store the configuration.

• The module will now translate the incoming SSO claims from your Identity Provider (IdP) into the custom attribute names defined here.

Role Mapping

• In the Role Mapping section, enter the Group Attribute Name exactly as configured in your Identity Provider to fetch the user group information.
• Enter the Role Name received from the Identity Provider and map it to the appropriate Role Value field. In the Role Value field, enter the roles defined in your .NET application.
• For example: Map the IdP group Group1 or Group10 received under the UserGroups attribute to the corresponding role configured in your .NET application.
• After adding the required mappings, click on Save Role Mapping to save the configuration successfully.

Domain Restriction

• This feature can be used to restrict user access to the site based on the domain of their mapped "Email" Attribute.
• In the Email Attribute field, enter the attribute name that contains the user's email address as received from your Identity Provider (IdP).

• In the Domain Name field, enter the domain(s) you want to allow or restrict, separated by commas if adding multiple domains.
• Enable the Restrict toggle based on your requirement to configure blacklist or whitelist access.
• After completing the configuration, click on Save Domains to save the settings successfully.

• These steps allow you to retrieve the SSO user information in your application in the form of session.
• You can also look the setup tour to understand how the SSO integration would work in your asp.net module application.
• Just copy-paste that code snippet wherever you want to access the user attributes.

• Hover on Select Actions and click on Copy SSO Link.
