EAP TTLS, RADIUS R0kd and WM

Not sure if this goes here but Ill ask anyways.

I have a WM 3 deployment and need to deploy EAP TTLS to a SOLO/DUO Mesh infrastructure.

Anyone have good documentation on deploying RADIUS/R0kd and EAP TTLS with WM 3? Im only finding scattered information about it on each device and everything for WM seems to be for an older version.

Thanks
