Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Federated Identity patternDelegate authentication to an external identity provider. This can simplify development, minimize the requirement for user administration, and improve the user experience of the application. Context and problemUsers typically need to work with multiple applications provided and hosted by different organizations they have a business relationship with. These users might be required to use specific (and different) credentials for each one. This can:
Users typically prefer to use the same credentials for all these applications. SolutionImplement an authentication mechanism that can use federated identity. Separate user authentication from the application code, and delegate authentication to a trusted identity provider. This can simplify development and allow users to authenticate using a wider range of identity providers (IdP) while minimizing the administrative overhead. It also allows you to clearly decouple authentication from authorization. The trusted identity providers include corporate directories, on-premises federation services, other security token services (STS) provided by business partners, or social identity providers that can authenticate users who have, for example, a Microsoft, Google, Yahoo!, or Facebook account. The figure illustrates the Federated Identity pattern when a client application needs to access a service that requires authentication. The authentication is performed by an IdP that works in concert with an STS. The IdP issues security tokens that provide information about the authenticated user. This information, referred to as claims, includes the user's identity, and might also include other information such as role membership and more granular access rights. This model is often called claims-based access control. Applications and services authorize access to features and functionality based on the claims contained in the token. The service that requires authentication must trust the IdP. The client application contacts the IdP that performs the authentication. If the authentication is successful, the IdP returns a token containing the claims that identify the user to the STS (note that the IdP and STS can be the same service). The STS can transform and augment the claims in the token based on predefined rules, before returning it to the client. The client application can then pass this token to the service as proof of its identity.
Federated authentication provides a standards-based solution to the issue of trusting identities across diverse domains, and can support single sign-on. It's becoming more common across all types of applications, especially cloud-hosted applications, because it supports single sign-on without requiring a direct network connection to identity providers. The user doesn't have to enter credentials for every application. This increases security because it prevents the creation of credentials required to access many different applications, and it also hides the user's credentials from all but the original identity provider. Applications see just the authenticated identity information contained within the token. Federated identity also has the major advantage that management of the identity and credentials is the responsibility of the identity provider. The application or service doesn't need to provide identity management features. In addition, in corporate scenarios, the corporate directory doesn't need to know about the user if it trusts the identity provider. This removes all the administrative overhead of managing the user identity within the directory. Issues and considerationsConsider the following when designing applications that implement federated authentication:
When to use this patternThis pattern is useful for scenarios such as:
This pattern might not be useful in the following situations:
ExampleAn organization hosts a multi-tenant software as a service (SaaS) application in Microsoft Azure. The application includes a website that tenants can use to manage the application for their own users. The application allows tenants to access the website by using a federated identity that is generated by Active Directory Federation Services (AD FS) when a user is authenticated by that organization's own Active Directory. The figure shows how tenants authenticate with their own identity provider (step 1), in this case AD FS. After successfully authenticating a tenant, AD FS issues a token. The client browser forwards this token to the SaaS application's federation provider, which trusts tokens issued by the tenant's AD FS, in order to get back a token that is valid for the SaaS federation provider (step 2). If necessary, the SaaS federation provider performs a transformation on the claims in the token into claims that the application recognizes (step 3) before returning the new token to the client browser. The application trusts tokens issued by the SaaS federation provider and uses the claims in the token to apply authorization rules (step 4). Tenants won't need to remember separate credentials to access the application, and an administrator at the tenant's company can configure in its own AD FS the list of users that can access the application.

FeedbackSubmit and view feedback for What is passed from the service provider to the identity provider in a federated solution?SAML works by passing information about users, logins, and attributes between the identity provider and service providers. Each user logs in once to Single Sign On with the identify provider, and then the identify provider can pass SAML attributes to the service provider when the user attempts to access those services.

What is a federated identity solution?Federated identity allows authorized users to access multiple applications and domains using a single set of credentials. It links a user's identity across multiple identity management systems so they can access different applications securely and efficiently.
What are the two components of a federated identity?Federated identity is based on a combination of several components including authentication, authorization, access control, IdPs, and service providers.
What is federation identity provider?By Rajeev Sharma. Federated identity management is a configuration that can be made between two or more trusted domains to allow consumers of those domains to access applications and services using the same digital identity.
