I've implemented Sitecore Social Connector to Login to my site using Facebook authentication as below:
ConnectUserManager connectUserManager = new ConnectUserManager();
if (!AuthenticationManager.GetActiveUser().IsAuthenticated)
connectUserManager.LoginUser("Facebook", true, (string)null);
else
connectUserManager.AttachUser("Facebook", true, (string)null);
It's able to authenticate for a few Facebook users. But, for some of them I get
authResult=error_f01edd48-d480-45b2-94fb-ce1b9b88568a#_=_
Username and password provided are correct. Any idea on what might go wrong here?
