Access OmniAuth strategy's configs

[Filippos Vasilakis]

How can I access strategy's configuration options that were set through the initializer in Rails? I really couldn't find anything. I looked through the code of the strategy that I use (omniaut-cas) but there is no such an option (configs are defined in 'instance' methods). I need to get somehow the initializer OmniAuth::Strategy::CAS object.
