Explanation:
Federated repositories enable you to use multiple repositories with WebSphere® Application Server. These
repositories, which can be file-based repositories, LDAP repositories, or a sub-tree of an LDAP repository, are
defined and theoretically combined under a single realm. All of the user repositories that are configured under
the federated repository functionality are invisible to WebSphere Application Server.
