Accessing EID Data

The EID System contains centralized identity information provided by the Source Systems and users. This information can be accessed for business purposes in a number of ways.


  • UTLogin is a centralized authentication service which supports web-based and stand-alone applications through standard authentication protocols.
  • It provides single sign-on capability for participating applications.
  • It provides support for common server platforms and third party applications.

uTexas Enterprise Directory (TED)

  • TED provides a consolidated, LDAPv3-based interface for use by university employees and departments.

  • It can be used to retrieve identity and affiliation information, authenticate UT EID holders when logging into departmental systems, and allow departmental systems to control access to resources based on information stored within TED.

Fat Cookie

  • The 'fat cookie' refers to a now-deprecated modified version of a normal browser cookie that wass encoded and digitally signed. The fat cookie contained biographical information about the user. It allowed services not deployed on specific administrative machines to use UT EID logon authentication. The Fat Cookie is being replaced by UTLogin.

University Community EID Listing

  • The University Community EID Listing is available to Members of the university community. Users can search for an EID by a number of criteria, and can view EID-holders' names, EIDs, department/college, address, date of birth and phone number. Clicking on the EID may display further information, depending on the user's authorizations. For instance, developers can view UIN.

Transitional Fat Cookie

  • In advance of the release of the Fat Cookie transition for Web Central customers by creating a Transitional Fat Cookie. The Transitional Fat Cookie will allow and other Web Central-hosted sites that use the Fat Cookie to continue to operate as expected after the Central Web Authentication (CWA) system is retired. After the Transitional Fat Cookie is fully deployed, visitors to EID-protected pages on Web Central will log in via the UTLogin sign-on page instead of the CWA sign-on page. Use of the Transitional Fat Cookie will end when sites are migrated to the new UT Web environment. Please email if you have any questions.
