Linux Directory Infrastructure Service (LDI)

Service Description

The core feature of LDI is that the directory stores and provides user account and group data which is synchronized with UW data sources for groups (Groups Web Service) and users (Person Web Service). This allows integration of Linux clients with common UW user data. Each campus unit which consumes LDI has a delegated organizational unit in the directory, has control over the synchronization process, and ability to add unit specific directory information.

Service Options

The LDI service is often used in conjunction with the Kerberos service to provide authentication. Details can be seen by following the link in the Additional Information section below.
