Abstract

An apparatus, program product, and method utilize 'dynamic' groups to represent collections of individuals in a computer environment. With a dynamic group, a group membership criterion and a set of member identifiers are associated with one another within a dynamic group data structure, such that the set of member identifiers identifies those users from a plurality of users that meet the group membership criterion for the dynamic group. Dynamic updates are performed periodically and/or in response to predetermined events, such that the set of member identifiers for a dynamic group are updated to reflect modifications to the plurality of users, and thereby maintain the identification of members in the dynamic group current. Dynamic group data structures may be utilized in connection with multiple networked target computer environments having users that span multiple computer domains and/or enterprises, wherein the target computer environments are networked with a hub computer upon which is resident a database that maintains a dynamic group data structure. Within at least a portion of such target computer environments, mirrored group data structures are distributed and maintained, with each including at least a subset of member identifiers from the set of member identifiers associated with the dynamic group data structure.
