A LDAP directory (the acronym stands for Lightweight Directory Access Protocol) is a hierarchical collection of attributes tuned to accommodate extremely fast searches and high throughput (along the order of 100,000 searches per second). HUIT’s LDAP directory acts as an official University attribute authority for anyone who has an Harvard University ID (HUID).
The Harvard LDAP Service offers a range of attribute data which vary accordingly by populations. The data on HUID holders includes multiple variations on their name, all core indicative and contact data, privacy data, and job and/or student status information. Note that the set of attributes for Alumni is more limited. Current uses of LDAP include:
- Authorization of application users to restrict access to an intranet
- Enhancement of applications with data, such as pre-populating forms to reduce user data entry
- Enabling access to administrative data for use by a billing system
- Providing an in-app directory reflecting individuals’ directory privacy preferences

Harvard LDAP Service Details
LDAP services are up and running around the clock. These services provide one foundation for Authentication and Authorization services.
The HUIT Identity Registry is the source of data for the Harvard LDAP. The Registry is updated daily from several source systems of record: the University Human Resource application, my.harvard (the student information system), the Division of Continuing Education's student information system, the Alumni application. Other updates are made using MIDAS (the source system for Library Borrowers) and the POI Portal (the source system of POIs - persons of interest). The HUIT Provisioning Service continuously updates the LDAP as data is updated in the Registry.
In 2018, previously separate directory instances were combined into a single instance. This ‘Harvard LDAP’ enables applications to integrate with a single instance for both authentication and authorization.
