I have downloaded and installed a brand new copy of Sitefinity 10 and am trying to test the new Social Authentication feature. I followed the instructions here (http://docs.sitefinity.com/administration-social-media) to configure my site to use Facebook Authentication. When I attempt to register an account using the Facebook option it prompts me to enter my credentials on the Facebook site. Once I log into Facebook, it returns to my site (sitefinitytest.com/sitefinity/authenticate/openid/callback?error=access_denied), but I get a popup in Windows asking me to authenticate and is preventing me from completing the registration with Facebook.
I get the same result with other OpenId providers as well. I have also tried this on a few different Sitefinity 10 installations and always get the same result.
Any help would be appreciated.
