In recent testing with iOS8 (specifically 8.0.2) we’ve discovered that any web application (in particular we’ve got a number of in house applications that were built using Visual Studio Lightswitch 2013) that relies on Windows Authentication (on Microsoft Internet Information Services) simply does not work.

In particular users get to the login prompt screen to enter their username and password and on attempting to login are just presented with the login window again with no apparent error message.

The work around for now is to use an alternative browser (Chrome works good for us), hopefully Apple will fix this annoyance soon.
