New! Grouper v1.4.2

Background
As a result of initial investigations by the MACE-Dir-Groups Working Group, Grouper was developed as an open source toolkit to address the needs of managing groups. Grouper is designed to function as the core element of a common infrastructure for managing group information across integrated applications and repositories. Grouper combines multiple sources of group information, both automated and manual, in managing memberships and other group information in a Groups Registry, a central information asset complementary to a site's Person Registry. A few of the benefits of a groups management service, such as Grouper, include:

• the same groups are made available to many applications
• distributed authorities are able to directly manage access information
• sophisticated group management capabilities, such as subgroups and composite groups, to support many access management needs.
• common user, web services, command line, and java interfaces for managing groups

In addition to basic group management and search capabilities, Grouper's design includes support for: basic group management by distributed authorities; subgroups; composite groups (whose membership is determined by the union, intersection, or relative complement of two other groups); custom group types and custom attributes; traceback of indirect membership; delegation.
