How to add attributes to Access-Accept replies

[Lucien RENAULT]

Hi,
I'm running a configuration where a Cisco 1600 router is running a PPPoE 
server and check user passwords against a freeRadius server running 
under FreeBSD.
This Radius server checks passwords against a LDAP database running on 
another BSD server.
The authentication is working great, the Radius replies with an 
"Access-Accept" reply to the Cisco router but it seems that the router 
needs two attributes to accept this reply :

Service-Type = Framed-User,
Framed-Protocol = PPP,

So I did the following configuration in users.conf :

DEFAULT Framed-Protocol == PPP
    Service-Type = Framed-User,
    Framed-Protocol = PPP,
    Fall-Through = Yes

But freeradius still replies with no attributes in Access-Accept 
packet... I read a lot of documentation about this and I'm quite 
confused since I don't really see any other mean to add attributes to 
replies...

Any Ideas ?

Thanks
