The specific configuration works fine I remove the following line from users 
	Tunnel-Type := VLAN, Tunnel-Medium-Type := IEEE-802, Tunnel-Private-
Group-ID := 218

In this case the user is placed in the vlan 220 (the statically configured in 
the accesspoint).

This could be the problem, I found something in the Cisco documentation but 
was unsure the problem could be this. The accesspoint is running

Cisco IOS Software, C1130 Software (C1130-K9W7-M), Version 12.4(10b)JDA3, 

I will try to verify what you say on the cisco site. My accesspoints are End 
Of Life, I do not know if any new IOS version has been developed to eventually 
correct the problem you say.

eap.conf (in peap stanza) says:

copy_request_to_tunnel = yes
use_tunneled_reply = yes
