Sorry I mean are you syncing primary groups or secondary groups from XenForo?

I think I fixed some of the issues that you might have been having Bara with my latest commit. Let me know if it works for you.

does this addon work with 2.1

I don't think so. Based on this line it should work with XenForo 1.5. So far i know with XenForo 2.x it was changed from "xf_user_external_auth" to "xf_user_connected_account". I'm pretty sure this needs some changes to get it compatible to XF2.1.
