Can I restrict users connecting via Facebook Connect?
This should be quite achievable.
Imagine a login page for your site where the user has to log in using Facebook Connect. (See " " Authenticating Users with Facebook Connect ") Once they are logged in, you will be presented with a Facebook Session ID specific to that user. You can use this Session ID to request information about a user, or inside a page using Javascript API libraries, or on the server side (see " Using Facebook Connect with the Server Side Libraries ").
One of the API calls: groups.get , which returns the groups the user is in. You should be able to get associated user groups after they have logged in to Connect, and as part of a page load test to see if they are in the correct group. If they are not, just redirect them accordingly.
