WARNING: This page is retained as a historical record but is out-of-date and is not being maintained.

This was a working document belonging to the Computing Service's Shibboleth Development Project. This project is complete (Raven now supports Shibboleth) and this document only remains for historical and reference purposes. Be aware that it is not being maintained and may be misleading if read out of context.

This is an attempt to map terms commonly used in the wider Shibboleth community onto words or phrases for use within the University of Cambridge, notably in the Raven/Shibboleth service itself and in its documentation.

eduPerson Principal Name An attribute containing a persistent, unique user identifier which for a given user is the same for any resource to which it is released, or the value of such an attribute.
