Affiliate Class

An EID class representing people with a significant relationship with the university, such as donors, library patrons, and former faculty, staff, and students.


Specifies a person's relationship (or relationships) to the university in very broad terms. At any point in time, an individual may have no defined relationship, one defined relationship, or many defined relationships with the university.

Affiliation Sponsor

University department that can add or remove an affiliation for an EID.

Assurance Level

In the old EID system: The level of confidence that the user was an actual person. There were 5 assurance levels: High, Pending High, Medium, Low, and Pending Low. High assurance (and pending high within the grace period) conferred power of electronic signature. This concept has been deprecated with the TIM system (circa 2006).

Authentication (Logon) Status

Defines whether an EID holder is able to log in with their UT EID and password. Possible values are initial, active, and inactive. Initial means the EID holder has never logged in using their UT EID and password, but can do so if desired. Active means the EID holder can log in. Inactive means the EID holder cannot log in because the EID is locked.


Business EID

An EID that describes a business entity. This kind of EID cannot be used to log in. Business UT EIDs always begin with the number '2', followed by a random sequence of numbers and letters.



A way to group affiliations into sets that have similar characteristics. There are three EID classes — Guest, Affiliate, and Member. An EID can belong to only one EID class at any time, as determined by the EID's affiliations.

Custom User Interface

A customized look and feel for the EID Self-Service Get an EID process that may use a template other than the standard UT EID Self-Service Tools template.


Department EID

An EID that describes a department in the university Department System. This kind of EID cannot be used to log in. Department UT EIDs always begin with the number '3', followed by the one-byte institution code and the department code from the Department System.



Electronic Identifier. A record within the EID system that includes the attributes UIN and UT EID.

EID Contact

An individual who can provide EID help (including the ability to reset a UT EID password) to an EID holder. The EID holder's affiliations or populations determine their EID contacts.

EID User Support Staff

University staff who provide support for EID holders. Such support may include, for instance, resetting passwords or upgrading EIDs.

EID Type

A category of EID defined by what kind of entity it represents. Each EID type has specific business rules and properties. There are seven EID types: person, business, department, id-only, service, group and resource.


A set of rights to a set of resources. An EID holder may have many entitlements, each with a start and end date (end dates may be in perpetuity).


Fat Cookie

A now-deprecated modified version of a normal browser cookie that was encoded and digitally signed. The fat cookie contained biographical information about the user. It allowed services deployed on machines other than specific administrative machines to use UT EID logon authentication. The Fat Cookie was been replaced by UTLogin, which was then replaced by Enterprise Authentication.


Group EID

An EID that describes a group of EIDs, used internally within the EID System. This type of EID cannot be used to log in. Group UT EIDs always begin with the number '5', followed by a random sequence of letters and numbers.

Guest Class

An EID class representing people with a very loose connection to the university, such as prospective students. This category also includes those with no affiliation.


ID-only EID

An EID that serves as an identification "tag" for a record. This type of EID cannot be used to log in. ID-only EIDs always begin with the number '0', followed by a random sequence of letters and numbers.

Member Class

The process by which the records associated with two different EIDs are linked to one, surviving, EID. Only person EIDs can be merged.


Non-person Record

A record that represents something that cannot be defined as a person, such as a business, department or service.


Permanent EID (PERM)

In the old EID system: A permanent, unique identifier used by the University of Texas at Austin. The Permanent EID is automatically generated, is not considered to be part of a person's directory information, and should remain confidential. It is used by several areas as the primary key on database records. This concept has been deprecated with the TIM system (circa 2006).

Person EID

An EID that refers to records representing a person. Person EIDs can be used to log on. They are formed using the initials of the individual and a sequence number. (UT EIDs issued prior to 2002 were not required to follow this format rule.)
