The Shibboleth System is a standards based software
package for web single sign-on across or within organizational boundaries.
It supports authorization and attribute exchange using the OASIS SAML 2.0
protocol. Shibboleth allows sites to make informed authorization decisions
for individual access of protected online resources while allowing users to
establish their identities with their local authentication systems.
.
This package contains the Shibboleth Apache module for service providers
(web servers providing resources protected by Shibboleth) and the
supporting shibd daemon.
