Have you tried this yet? I’ve gone round and round with Microsoft over this but I guess that it’s just not possible. If you have an App Part that is trying to read from a list inside your App using REST, it will not allow this as an anonymous user. Has anyone come up with a solution for this problem or am I not seeing things correctly?
Yes. I’ve been part of those discussions. I even have my own thread on the same subject. http://social.msdn.microsoft.com/Forums/sharepoint/en-US/d6e32214-43a1-468c-942c-810e09dd9597/access-denied-app-part-on-anonymous-public-facing-site
It just doesn’t make sense to me that I cannot give read rights to a list for anonymous users inside an App. So basically, Microsoft is saying that Apps in Anonymous sites are useless.
