This document will help you setup your service provider to integrate with the Wisconsin Federation.
Some web applications need to be accessed by users of other UW-System campuses (outside of UW-Madison). This document will outline the changes you need to make to your shibboleth2.xml to make your Service Provider (SP) work with the Wisconsin Federation (WiscFed) Identity Provider (IdP). You will also have to fill out an Identity Data Integration Request Form to access UW-System identity data.
The signing certificate for the SP can be retrieved at https://wayf.wisconsin.edu/metadata/wayf.wisconsin.edu-signing.pem.
