General Information [1]

EduPerson is a auxiliary object class for campus directories with the aim to facilitate communication among higher education institutes on the basis of an campus directory (an integrated institutional data store, which provides authorized users access to information regardless of where or how the original information is stored). It consists of a set of data elements or attributes about individuals, along with recommendations on the syntax and semantics of the data that may be assigned to those attributes.

Benefits of eduPerson
Many of the eduPerson attributes are intended to support inter-realm applications such as ShibbolethLogging-in system for computer networks (inter-realm authentication).

Attributes of eduPerson
Two types of attributes:

  1. Attributes already given in most commercial directory server products (like names, email addresses)
  2. Attributes newly created to facilitate inter-institutional collaborations and applications

Each attribute has an application utility class which suggests the class of application for which this attribute is appropriate. Three of these classes are defined as followes:

  • Core
All attributes which provide the minimum useful bits of information about a person in a dictionary. This attributes are cn: common name, sn: surname and eduPersonOrgDN: the person’s affiliation’s distinguished name
  • Standard
An expanded list of attributes that (complemented with the core attributes) are adequate to support a full-featured directory. That class includes attributes useful for role-based access control decisions.
  • Extended
The rest of the defined attributes, which support a larger class of potential applications.
