Hello, I use FreeRadius with OpenLDAP to authenticate device using EAP-PEAP and it works fine. The only problem I had was the encrypted password in my LDAP database. I by-passed this problem using clear-text Password in LDAP Database and it works fine. You can also have a look at this : http://deployingradius.com/documents/protocols/compatibility.html
