Windows single sign-on for web clients

Yesterday during the session ID101 "New Single Sign-on Improvements for your IBM Lotus Notes and Domino Windows Environments", we had a big news for Domino: IBM are working on the Windows single sign-on for web clients. Based on spnego, it will work only between Windows system (client and server).

Hope they will release this soon, in the slides they use the term "future release". Domino 8.5.x? Domino 9? Who knows ... will see.
