Version 3 of the Identity Provider is under active development. As such, this documentation is incomplete and also under development.
A beta release has been produced, and this space contains the minimal documentation we're able to produce for that testing.
Below is the documentation available for version 3.0 of the Shibboleth Identity Provider. Documentation is split up in to two parts: documentation meant for individuals that are deploying and managing an Identity Provider and documentation meant for individuals that are developing custom extensions for the Identity Provider.
Upon the release of V3.0.0, expected in mid-December, it will become the current stable release of the Identity Provider, and V2.4.3 will become the previous stable release. The consortium has not made a final decision, but the expected EOL date for the V2 code base is the end of 2015.
