As a prospective candidate for the SC-300 Microsoft Identity and Access Administrator exam, understanding federation is fundamentally important, particularly how to implement and manage it. For the purposes of this article, we will focus more on Federation excluding manual AD FS deployments.
Federation is essentially an agreement between organizations (a federation) to trust each other’s identifying information. In the context of Microsoft Identity Platform, it involves the integration of an organization’s Active Directory with Office 365, Azure AD, and other SaaS applications.
Active Directory Federation Services (AD FS)
Though we won’t go through manual AD FS deployments, it is still crucial to have a basic understanding of it given that it plays a crucial role in the federation process. Secure and seamless access to applications and services by using Single Sign-On (SSO) is facilitated by Active Directory Federation Services (AD FS). It uses a claims-based access control authorization model, which means it authenticates users by validating the correctness of their claims.
Implement and Manage Federation
Implementing federation has several steps. Here, we will focus on the non-manual parts of the operation.
1. Azure AD Connect
Object synchronization, password hash synchronization, Pass-through Authentication, Federation integration, or Health Monitoring for your cloud and on-premises infrastructure are all options with Azure AD Connect. Azure AD Connect synchs your on-premises directories with Azure Active Directory, ensuring that users have a consistent set of properties.
2. Seamless Single Sign-On (SSO)
With Azure AD Seamless SSO, users can automatically sign into both on-premises and cloud-based applications when they are signed into their corporate devices inside the corporate network. In terms of initial setup, user sign-in behavior, application support, and user provisioning, Azure AD Seamless SSO differs from AD FS.
Here the comparison of Azure AD Seamless SSO and AD FS:
| Azure AD Seamless SSO | AD FS |
|---|---|
| Easy to setup | Requires significant planning and setup |
| Signs users in when they’re on their corporate machines | Allows sign-in from all devices |
| Works with all web browser-based applications | Supports modern authentication protocols |
| Free feature of Azure Active Directory | Requires Windows Server licenses |
3. Configuring Federation with PingFederate
PingFederate offers seamless, high-quality, secure single sign-on access to all users across all applications, reducing the administrative burden of the IT staff and the password fatigue experienced by users.
A working agreement can be established between a PingFederate server (as an identity provider) and Microsoft Azure AD (as a service provider), allowing PingFederate to authenticate users for the Azure AD domain.
In conclusion, to successfully pass the “SC-300 Microsoft Identity and Access Administrator” exam, it is crucial to understand how to implement and manage federation services. Although this article does not focus on manual Active Directory Federation Services deployments, it does provide insights into the key tools like Azure AD Connect, Azure AD Seamless SSO, and PingFederate. The key is to understand each one and know how and when to use them to ensure secure and seamless access to both on-premises and cloud-based applications.

Interview Questions
What is federation in the context of identity management?
Federation, in the context of identity management, is a process that allows for single sign-on between two partnered systems. It allows the sharing of identity attributes between the systems whilst reducing the need for duplicate account management.
What is Azure AD Connect used for?
Azure AD Connect is a tool that is used to synchronize identity data between on-premises Active Directory and Azure Active Directory. It supports complex deployment topologies and hybrid identity solutions.
What is the primary authentication method used in a federation scenario?
The primary authentication method in a federation scenario is Token-based authentication, where users are authenticated by their managing system, that then allows secure communication between partnered systems.
What are the main purposes of the Azure AD federation settings?
The main purposes of Azure AD federation settings are to manage and configure federation partners and settings, the attribute to be used as the unique identifier for federation, and to ensure secure communication between systems.
What is Azure AD B2B Collaboration?
Azure AD B2B Collaboration is a service that enables organizations to share applications and services with external users while maintaining control over corporate data.
What are some advantages of implementing federation, excluding manual AD FS deployments?
Some advantages include single sign-on (SSO) for users which reduces password fatigue, improved security due to reduction in stored username and password data, and lowered support costs related to password management.
How can a user from a federated domain access resources in Azure AD?
A user from a federated domain can access resources in Azure AD by signing in with their on-premises credentials. Azure AD forwards the user’s authentication request to the on-premises federation server, which then validates the user’s credentials.
What is the Microsoft Online Services Sign-In Assistant?
The Microsoft Online Services Sign-In Assistant provides end user sign-in capabilities to Microsoft Online Services such as Office 365. The assistant is a prerequisite for the installation of Azure AD Connect.
What is a Claims-based authentication?
Claims-based authentication is a process in which a user’s identity is authenticated by a third party, known as a Security Token Service (STS), by providing a set of claims.
Can Azure AD Connect be used to federate with multiple Azure AD tenants?
No, a single Azure AD Connect instance cannot be used to federate with more than one Azure AD tenant. Each Azure AD Connect instance can only be linked to a single Azure AD tenant.
When configuring federation with AD FS, what permission is needed for the account performing the setup?
The account performing the setup must have Global Administrator permissions, as it needs to perform functions such as changing the user sign-in method to Federation.
What is the purpose of syncing password hashes to Azure AD?
Syncing password hashes to Azure AD allows users to use the same password to sign in to Azure AD as the password they use to sign in to their on-premises Active Directory instance. This is generally accomplished via tools like Azure AD Connect.
Are there any fallback methods if federation fails?
Yes, if federation fails, you can use either Password Hash Synchronization or Pass-through Authentication as fallback authentication methods.
How is the sign-in activity recorded when users from a federated domain sign in to Azure AD?
Every time a user from a federated domain signs in to Azure AD, a log entry is created in the Azure AD sign-in activity report. This report can be accessed in the Azure portal.
Can you disable federation for a specific user in Azure AD?
No, you cannot disable federation for individual users. Federation settings apply to an entire domain in Azure AD. You can, however, convert a federated domain to a managed domain and then use alternative authentication methods for individual users.
