Setting up FreeRADIUS 2.0.4 with OpenLDAP backend to do wireless auth
Hi everybody. As the title says, I'm trying to set up FreeRadius to authenticate wireless clients (employees). I just finished deploying a Samba/Ldap domain, and I'd like to take advantage of this user db. I already followed several howtos, more or less outdated. For now, I can authenticate a user against my directory only with radtest. When I try from a Win XP laptop doing PEAP (in the wireless assistant), i cant get it to work. I'm not familiar with the bunch of protocols coming with radius and 802.1x (PEAP, CHAP, etc.), and I can't find the issue. Here is the trace of the server, with a connection attempt of the laptop.

Why not just install 2.1.8?
I'm not familiar with the bunch of protocols coming with radius and 802.1x (PEAP, CHAP, etc.), and I can't find the issue.
Read the debug output, and look for "peap". It is *telling* you why it isn't working. See also my web site for instructions on getting EAP to work: http://deployingradius.com Alan DeKok.
