Gw2014 Sp1 and SSO for AD

As i remember to read in a previous Gwavacon/Brainshare session, there was a roadmap for introducing Client Single Sign on to Active Directory with GroupWise 2014 SP1.
Sp1 is now released, but i don't see any of that feature! Is there a new timeframe for that?
Some of my customers are waiting to migrate, because of the need SSO to AD.
