I know others have asked the same question and know it cannot be done but I am trying to understand the technical reasons behind this. In ADFS 3.0 if I create an Additional Authentication Rule to target a specific user agent string then force forms authentication, this will not work. Why?
if you could tell us exact requirement please
Provide more detail, what exactly you want to achieve.
Right now when vendor supplied Droid device use an app that is federated it fails at a white screen since it is trying to use WIA. We were trying to use an additional authentication rule to filter on the user agent string then force forms authentication.
