Juniper and FreeRADIUS

Has anyone had any experience setting up a Juniper firewall using FreeRADIUS to do XAUTH? I am having trouble with the firewall doing authenticating. I have tested the RADIUS server with RADIUS test, check configuration and on both server and FW, see the FW talking to the server but when a valid user id and pass and put in through Netscreen Remote VPN client RADIUS server fails the authentication. Thanks in advance for the help!
