Completed: October 12, 2009

Description: Information about people that is used to control electronic access is maintained in multiple locations today. One of the sources is known as the Enterprise Directory Service, or EDS. Many enterprise applications, including OneStart and Oncourse, use the data in the EDS to manage access.

Originally conceived in 2007, the goal of this project is to migrate the information currently maintained in the EDS to another central directory service known as Active Directory, or ADS. In addition to being the primary source of authentication for CAS, network (VPN) access, and most workstations, Active Directory also contains a rich set of data about people at Indiana University, as well as records related to computers, groups, and other network resources.

Most of the applications that rely on the EDS also have a dependency on ADS, so migrating all person information from EDS into ADS will eliminate a redundant service, resulting in a number of benefits to users of enterprise applications at Indiana University. Among other things, improvements in efficiency will result in more accurate directory data.

The Active Directory schema will be extended, in two phases, to accommodate the additional person information. The first phase will consist of the Internet2 eduPerson schema. Phase II will be a revised version of the IU extensions to the Internet2 schema, known as iuEduPerson.

Once the schema extensions are complete, person data in AD will be updated and enterprise applications will begin to retrieve that data from AD.

Outcome: When the project is complete, the EDS will be completely eliminated. This includes numerous servers, as well as processes to support and maintain the environment. All of the enterprise applications that rely on the data in EDS will be able to rely on ADS for information about people as well as groups.
