    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.
    • You may refer to the screenshot below:
    • DNN SAML SSO - Upload Metadata Manually
    • 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 Update to save your IDP details.
    • DNN SAML SSO - Upload Metadata

    4. Test Configuration

    • Click the Test Configuration button to verify if you have configured the plugin correctly.
    • On successful configuration, you will get Attribute Name and Attribute Values in the Test Configuration window.
    • DNN SAML SSO - Keycloak test result

    5. Attribute Mapping

    • Attributes are user details that are stored in your Identity Provider.
    • Attribute Mapping helps you to get user attributes from your IdP and map them to DotNetNuke user attributes like firstname, lastname etc.
    • While auto registering the users in your DotNetNuke site these attributes will automatically get mapped to your DotNetNuke user details.
    • Go to DNNSAMLSSO Settings >> Advanced settings >> Attribute Mapping.

    • DNN SAML SSO - Attribute Mapping

    6. Adding Login/SSO Widget on DNN Page

    • For Adding Button on the DNN page on beside the module settings click on the Add Item (Pencil Icon).

    • DNN SAML SSO -  Add Login Button
    • Add Button name and click on Save.

    • DNN SAML SSO -  Save Login Button
    • You can see login button on the page after saving item. (If you are already logged in your site, you will see a "Logout" link).
    • Note: If you want to Enable this button on every page of the DNN site follow below steps:
    • Go to the Settings >> Module Settings >> Advanced Settings and Enable option for Display Module On All Page.

    • DNN SAML SSO - Module Settings
      DNN SAML SSO - Display Module on Multipages
    • Warning: You will lose all your configuration for the module after enabling this option. You can re-configure the module or it is better to enable this option before configuring the module.

    7. Role mapping (It is Optional to fill this)

    • DotNetNuke uses a concept of Roles, designed to give the site owner the ability to control what users can and cannot do within the site.
    • DotNetNuke has five pre-defined roles: Administrators, Subscribers, Registered Users, Translator (en-US) and Unverified Users.
    • Role mapping helps you to assign specific roles to users of a certain group in your IdP.
    • While auto registering, the users are assigned roles based on the group they are mapped to.
    • DNN SAML SSO - Role Mapping

    You can configure the DotNetNuke SAML 2.0 Single Sign-On (SSO) module with any Identity Provider such as ADFS, Azure AD, Bitium, centrify, G Suite, JBoss, Auth0, Okta, OneLogin, Salesforce, AWS Cognito, OpenAM, Oracle, PingFederate, PingOne, RSA SecureID, Shibboleth-2, Shibboleth-3, SimpleSAML, WSO2 or even with your own custom identity provider.
