Below is the documentation available for V3 of the Shibboleth Service Provider, including all 3.x patch and minor upgrade releases. Documentation is split up in to two parts: documentation meant for individuals that are deploying and managing a Service Provider and documentation related to building/developing it.
All software, including archived releases, is available from https://shibboleth.net/downloads/service-provider/ and each source and Windows release is accompanied by a detached PGP signature using one of the keys listed in the project's PGP_KEYS file.
All our software is licensed under the Apache 2.0 open source software license.
All deployers need to subscribe to the Shibboleth Announcement mailing list. This is where announcements about new releases, end of life of past releases, and are distributed.
High-level information to get started with SAML and Shibboleth can be found in thewiki space.
