AP with Radius and VLAN?

[Frank Rizzo <thefrankrizzo hotmail com>]

Hey guys!

I'm using Ubuntu 14.04 LTS, and using the applet I am able to do basic  
configuration of an AP.  I can then start it, connect to it, and use it.   
But this base config is very simplistic.  I need something more.  I need  
Radius server authentication, and VLANs.  (Things that are supported  
through hostapd).

Does anyone have an example config that I can base mine upon?

Thanks!
