LDAP FreeRadius and DLINK DWC.

13 Oct 2015

      Hi All,

We are looking at trying to implement WPA Enterprise with LDAP Auth, 
FreeRadius using a DLINK DWC-1000 Wifi Controller.
I have spent the day trying to determine if the new version 3.0 and the 
inner tunnel now allows this to work
over older versions and mailing list entries saying this will never work 
and I cant seem to figure a straight answer.

We are using radiusd: FreeRADIUS Version 3.0.4, for host 
x86_64-redhat-linux-gnu, built on Mar  5 2015 at 23:41:36
on a centos 7.1.1503 machine. The DWC is the latest firmware.

I have read the guide in the inner-tunnel file and attempted the radtest 
and it even fails at the simple chap auth,
but works perfectly at the pap test. ( Debugs below ).

Am I kidding myself this actually works with LDAP or just got the config 
wrong ?. Changing to username and password
in files works perfectly for all methods of auth.

Thanks in Advance
Martin

Debug follows. ( for the radtest )
