When our SharePoint 2010 intranet login page loads on desktop PC'S, our Windows Authentication link shows up, this way members can log-in properly. But for some reason, specifically with iPhones and Droid Smart Phone devices, we get the login page but no request for windows authentication. So my question - how can we apply Windows Authentication to log-in form pages, if the user is coming from an iPhone or Droid?
FYI - once the user hits our main intranet page, SharePoint is redirecting mobile users to a custom mobile form page under my /_layouts/ directory, which has no activity of windows authentication for some smart phones. I really want to figure out how to apply windows authentication to the custom form under my _layouts/ directory for all smart phone device users.
Thanks for any advice!
