What identity system allows multiple organizations access to a shared NoSQL cloud database?

1. Single sign-on

2. Federations

3. LDAP

4. Authorization manager

The correct answer is: Federations

Federations are designed to facilitate collaborative identity management across multiple organizations. This approach allows different entities to maintain their own user identities while establishing a trust relationship that enables users from one organization to access resources in another organization. In the context of a shared NoSQL cloud database, federations permit seamless authentication and authorization for users from various organizations, enabling them to interact with the database securely without the need for separate credentials for each organization. Single sign-on primarily deals with allowing users to log in once and gain access to multiple applications or services without needing to re-enter credentials, but it does not inherently establish cross-organizational access. LDAP, or Lightweight Directory Access Protocol, is a protocol used to access and maintain distributed directory information services, but it typically manages identity within a single organization rather than across multiple entities. An authorization manager is more focused on defining and enforcing policies regarding what resources can be accessed, but it does not specifically address cross-organizational access mechanisms. Thus, federations are specifically tailored for scenarios where multiple organizations need coordinated and secure access to shared resources, making it the most suitable option for the question.
