> - Cisco Aironet 1130AG access point
> - Ubuntu-based server with FreeRADIUS and OpenLDAP
> - Client machines (Windows XP SP2, Ubuntu 9.04)
> The issue I have is, that I don't get a response from the client after the

> bootstrap script of FreeRADIUS, so it already contains the OIDs required
> The AP is configured correctly, IP-address, port numbers and shared secret

> Users are stored in an LDAP database and each user has a sambaNTPassword

Post the debug.
