Freeradius with OpenLDAP (Suse Enterprise 10)

LDAP is installed and working out of the box, having been set to be used 
for authenication during the SUSE install.

This is proven by the ability to log in to the box, both locally and via SSH

I installed freeRADIUS from the latest source and it is working also.

freeRADIUS seems unable to find a password for the user during 
Authenication.

I issue the following on my workstation

david at belld-ubuntu:~$ echo "User-Name = belld,Password=p455w0rd" | 
radclient 212.95.255.242:1812 auth testing
Received response ID 99, code 3, length = 20

And see the following from freeRADIUS 

Listening on authentication address * port 1812
Listening on accounting address * port 1813
Ready to process requests.

What I cant work out is whether this is due to an LDAP or a RADIUS 
config problem.
