Which two server types can be used as federated identity sources in a StorageGRID environment?

In a StorageGRID environment, federated identity sources play a crucial role in enabling single sign-on and managing user authentication. The server types that can serve as federated identity sources must support industry-standard authentication protocols, allowing for seamless integration with StorageGRID's identity management features.

LDAP (Lightweight Directory Access Protocol) and Active Directory are both widely used directory services that provide authentication, user management, and authorization functionalities. They are designed to support federated identity management and can communicate using protocols such as SAML (Security Assertion Markup Language) and OAuth, making them suitable for use as federated identity sources in StorageGRID.

In contrast, SQL Server and MySQL are relational database management systems primarily used for data storage and manipulation rather than user authentication and federation. Similarly, Oracle is also a database platform, and SAMBA is a suite of programs that enable file sharing, which does not directly relate to identity federation in this context. Lastly, HTTP and FTP are protocols for transferring data over a network and do not serve as identity sources.

Therefore, the selection of LDAP and Active Directory as federated identity sources is correct, as they are the two server types specifically designed for managing identities and authentication in a way that aligns with StorageGRID's capabilities.
