Ilan Tochner who is the CEO of the Kitely grid announced on 20th March via the Kitely Forums and the Kitely blog that support for Facebook Groups as access controls for worlds will be removed as of Friday 27th March 2015.
It seems like Facebook has decided to stop allowing external programs to get the list of groups that a user belongs. Kitely will be removing this feature and support for it later this week. For more details see below.
Via the Kitely Forums thread…
We’ll be removing support for Facebook Groups as access controls for worlds on March 27. If you’re currently using this feature then make sure to change your world access controls before this date.
Via the Kitely blog post…
Currently, World Managers can choose to restrict access to their worlds so only people who belong to certain Facebook Groups can visit it. Unfortunately, Facebook has decided to stop allowing external programs to get the list of groups that a user belongs to. Therefore, we are forced to remove this feature from Kitely. This will happen on March 27, 2015.
If you are currently using Facebook Groups for access control then you should switch to a different method of restricting access to your world: e.g., using OpenSim groups. Otherwise, once we’ve updated the system your world may become accessible to more people than you had intended.
