Hitachi ID Group Manager is currently designed to target a single platform -- Active Directory. Its user interface exposes resources that are typically made accessible by user membership in AD groups:
Group Manager uses plugins to connect to target platforms. The Windows/AD resource discovery plugin is able to drill down into Windows-based network resources, find out which groups have rights to which resources, and lookup group owners on Active Directory. The Hitachi ID Identity and Access Management Suite Active Directory connector, included with Group Manager, can enumerate AD users and groups, authenticate AD passwords and update AD group memberships.
