Did you get the solution?
I think the issue might have occurred on the Social Login side.

Subject: [FACEBOOK] Social Login ClearPass Require Field unavailable!!!
I'm having this same issue...sometimes.
The MAC address is there, but when I click the social login button I get the Required Field Unavailable error. At that point, the mac address is now gone from the URL.
If I click back in my browser and click one of the social login buttons again, it works fine.
