[quote author="Anna_FL" date="1291105858"]Jakub, thank you very much for this guide!!!!
Does anyone know how to setup the GET URL structure needed for Google's authentication? Or if we really need to do that or is there a hack using $_POST?
Thanks again[/quote]
Anna, based on my setup, I have all methods working (haven't tested Facebook tho).
I tested the following:
Google, Yahoo, OpenId (via myopenid), and twitter... all working so far.
Make sure to double check your permissions, as that could be causing problems with authentication if you are getting failures.
