Groups in a directory service or LDIF file are hierarchical. StarTeam groups are also hierarchical, but, in Caliber, no group is a subgroup of another.
When you import a hierarchy of groups into StarTeam, that hierarchy is maintained in the new location.
When you import a hierarchy of groups into Caliber Server, the hierarchy disappears. If two imported groups have the same names, they are combined into a single group. For example, suppose during one import operation, you import a group named Detroit along with its two subgroups, Managers and Workers. This import operation would result in three new groups in Caliber: Detroit, Managers, and Workers. No parent/child relationships would be preserved. Suppose that you later import a group named Toronto and its two subgroups named Managers and Workers. The end result in Caliber would be four groups: Detroit, Toronto, Managers, and Workers. The Managers and Workers groups would contain users from both Detroit and Toronto, while the Detroit and Toronto groups might be empty.
