Groups are used to manage user access. Groups are containers which can hold permissions, roles and users. When a user is assigned to a group, they inherit any roles or permissions that have been allocated to that group.
There are four built-in groups: Administrators, Dimension Maintainers, Meta Admin and Publish Administrators. These groups contain pre-configured roles with specific system access which cannot be changed.
Group Management is used to manage Groups (create, edit and delete) as well as to assign both users and Roles to Groups.
