In most cases, Texas Digital Library uses the Shibboleth federated identity application to connect each hosted institutional repository to the institutional identity provider for the member institution. When a user logs in via Shibboleth, they log in to their home institution’s identity system, and that system passes along a limited set of attributes to the DSpace platform to authenticate the user. Those attributes typically include:
Name (visible only to the user and Administrators)
Email Address (visible only to the user and Administrators)
Institutional Affiliation (used for authentication only and not visible in the user interface)
A unique alphanumerical identifier (used for authentication only and not visible anywhere in the user interface)
