I have Cisco Aironet 1100's that I am setting up on a private LAN that
go through a Firewall to get to the internal LAN. The FreeRadius server
is on the internal LAN.
Ok, so what works: I can connect the client (supplicant) to the
Wireless G Aironet that authenticates to the FreeRadius Server. I can
then connect to the VPN (which also authenticates to the Radius
server). Everything there is happy.
What does not work: The Aironet's use a system called WDS to allow
roaming between the access points. I set up one unit to be the primary
WDS, and configure a second Aironet to use WDS. The Aironets use the
Radius server for authentication, but they never are able to
authenticate with the WDS.
What I think I am doing wrong: I believe that I need to activate peap
for the Cisco Aironets to authenticate. I have tried to set this up per
documentation, but I get the following error when I now try to activate
the FreeRadius server using radiusd -A -X, cut to just show the eap
module failure:

I have tried to use CA.all to create a certificate, but it gives an
error during the certificate creation. I have created a certificate
manually using openssl, and moved it into the /usr/local/etc/raddb/certs
folders (and DemoCA folders), but the server still fails.
I am running RedHat 9, kernel 2.4.20-8smp; openssl-0.9.7a-2;
freeradius-0.9.3-1.1
Does anyone know if the peap is even needed with the Aironets? If so,
is there another howto or other docs I can RTFM to resolve this
certificate issue, or do I just need to hack all of the config files,
CA.all, etc... Has anyone got this type of setup working (Cisco
Aironet's running WDS and FreeRadius)?
