Tutorial / Cram Notes

Configuring identity providers is a critical task for any Identity and Access Administrator, especially those preparing for the SC-300 Microsoft Identity and Access Administrator exam.

Identity providers (IdPs) allow users to authenticate using their existing credentials. Two of the most common protocols for web-based single sign-on (SSO) are Security Assertion Markup Language (SAML) and Windows Federation (WS-Fed).

Understanding SAML and WS-Fed

  • SAML (Security Assertion Markup Language):

    SAML is an open standard for exchanging authentication and authorization data between an identity provider and a service provider. In a SAML assertion, the identity provider sends a signed XML document to the service provider. SAML is widely used for web-based applications.

  • WS-Federation (Windows Federation):

    WS-Fed is a part of the larger WS-Security framework and is designed for integration with Windows-based systems. WS-Fed extends the WS-Security model to facilitate the transfer of identity information across security domains.

Configuring Identity Providers in Azure AD

When implementing SAML and WS-Fed for applications with Azure Active Directory, you must configure things properly to ensure seamless SSO experience for users.

Configuring SAML with Azure AD:

  1. Register the Application:

    First, you need to register the application in Azure AD that will use SAML. This can be done by navigating to the Azure portal > Azure Active Directory > Enterprise applications > New application.

  2. Set up Single Sign-On with SAML:

    Once the application is registered, configure the SSO settings by going to the application’s menu and selecting ‘Single sign-on’ and choosing SAML.

  3. Basic SAML Configuration:

    Input details like Identifier (Entity ID), Reply URL (Assertion Consumer Service URL), and Sign-on URL which are provided by the application vendor.

  4. SAML Signing Certificate:

    Azure AD then provides you with a SAML signing certificate which needs to be trusted by the application.

  5. Configure User Attributes & Claims:

    You can configure what pieces of information you want Azure to send to the application. This could include the user’s email, username, or other attributes stored in Azure AD.

  6. Configure on the Application Side:

    Finally, you’ll need to configure the SAML settings provided by Azure (such as the Sign-On URL, Azure AD Identifier, Logout URL, and Certificate) on the application that’s integrating with Azure AD.

Configuring WS-Fed with Azure AD:

  1. Register the Application:

    Similar to SAML, you first register the application within Azure Active Directory.

  2. Set up Single Sign-On with WS-Fed:

    Navigate to the Single sign-on method and choose WS-Federation to configure the details.

  3. Configure Application Settings:

    Enter the WS-Fed specific details such as the Passive Requestor Endpoint, and adjust settings as necessary for your application.

  4. User Attributes & Claims:

    Configure the user attribute claims that Azure AD sends to the application within the token.

  5. Application Side Configuration:

    The application needs to be set up to accept tokens from Azure AD based on the WS-Fed protocol. This may include setting the correct realm, endpoint URLs, and token parameters that Azure AD provides.

Comparison of SAML and WS-Fed

Criterion SAML WS-Federation
Protocol Standard OASIS Standard Part of the WS-Security standard
Token Type XML-based XML-based
Integration Broadly used with web apps Often used in Microsoft-centric environments
Complexity Can be complex to implement Simpler for Windows environments
Security Uses digital signatures and encryption Also uses signatures and encryption

It’s important to note that modern authentication protocols such as OpenID Connect and OAuth 2.0 are becoming more prevalent due to their simplicity and ease of use with mobile and modern applications. However, SAML and WS-Fed are still widely used, especially in enterprise environments where integration with legacy systems is necessary.

In conclusion, configuring SAML or WS-Fed requires a detailed understanding of both the application being integrated and Azure AD’s configuration options. By mastering these configurations, those preparing for the SC-300 exam can ensure that they can successfully support secure and seamless SSO experiences.
