Which identity management method allows for single sign-on (SSO) through the handling of login requests by an on-premises identity provider?

The concept of federated identity is central to enabling single sign-on (SSO) capabilities. Federated identity management allows multiple systems to share identity information across different domains while maintaining a single identity for the user. This method relies on an on-premises identity provider that handles authentication requests and issues tokens or assertions to access resources across various systems or applications.

With federated identity, users can log in once and gain access to a variety of services and applications without needing to re-enter their credentials for each separate service. This seamless access improves user experience and reduces the burden of managing multiple passwords.

In contrast, the other options do not specifically address the SSO functionality driven by an on-premises identity provider. Cloud Identity focuses more on cloud-based authentication solutions, Role-Based Access Control is a method for managing access permissions based on user roles rather than a technique for SSO, and Hybrid Identity Management integrates both on-premises and cloud identity management, but may not exclusively emphasize SSO. Therefore, the best fit for enabling SSO through an on-premises identity provider is federated identity.
