I created a SharePoint App, but each time I am trying to access it I keep getting pop up authentication window. I am trying also with other apps from the SharePoint store, which makes me think the problem is with the configuration of my app services themselves.
I followed the article: http://sharepointchick.com/archive/2012/07/29/setting-up-your-app-domain-for-sharepoint-2013.aspx . Is there any extra step to do? It's only on my development environment as I don't want to use O365. I am not connected to internet always.
Environment: SharePoint 2013. windows server 2012.
