Shibboleth is a higher education community implementation of web single-sign-on using the SAML protocol. The Shibboleth Service Provider can often be used as a replacement for CUWebAuth. The advantage of using Shibboleth is that you can enable access to your site to users from other institutions that are members of the InCommon Federation (see next paragraph). You can restrict access to include only certain members of InCommon and/or people at member institutions who have certain attributes, such as faculty, student, etc.
Cornell is a member of the InCommon Federation, which is a group of 400+ higher education institutions (including Cornell, Columbia, Stanford, Ohio State, and many others) and service providers (including Microsoft, EBSCO, OCLC, and JSTOR) that trust each other's authentication systems (NetIDs). See the InCommon Federation article for more information and a list of college and university members.
Weill Cornell maintains its own, separate Shibboleth identity provider.
SAML is also a popular method for enabling cloud vendor sites to authenticate and authorize Cornell users. Some examples are Workday and Box.com. Integrators outside of InCommon who would like to make use of Cornell's Identity Provider may point to the test IDP first and work through any initial issues. When you are ready to move your integration into production, please submit a request to start the production integration process. Cornell Information Technology requires that all new service providers include a certificate for encryption in the metadata.
