A Service of IET

Shibboleth federated single sign-on authentication service is a standards-based, open source software package for web single sign-on across or within organizational boundaries. Shibboleth, a project of the Shibboleth Consortium, allows institutions to make authorization decisions for individual access of protected online resources. The Shibboleth software implements widely used federated identity standards, principally OASIS' Security Assertion Markup Language (SAML), to provide a federated single sign-on and attribute exchange framework. Using Shibboleth-enabled access simplifies management of identity and permissions for organizations supporting users and applications. Shibboleth is developed in an open and participatory environment, is freely available, and is released under the Apache Software License.
