A collaboration admin can create groups within the collaboration and assign people to them. Whenever a user logs in into a service connected to that collaboration, their group membership information is released to the service. The service can use that information for authorization: deciding who is allowed access to what functions or data. For example, if a user must be assigned an admin role in the research service, create a group 'admin' in SRAM and configure the service to automatically assign users with that group membership the admin role in the service.
