Shiboleth Authentication for Zend Framework 2

Some time ago I wrote a simple Shibboleth authentication adapter for ZF1. Now I finally began using Zend Framework 2 for more complex projects, which require Shibboleth authentication. So I wrote a new version of the adapter to be used with ZF2. It can be used as a module or as a standalone library. The code is available through Composer.
