free RADIUS server + return class attribute

[Vinay]

hi there,
I want to configure the freeRADIUS server to return the CLASS
attribute in the ACCESS-ACCEPT message,.
I tried adding the attribute for a user in users file :

vinay Auth-type:=CHAP,User-Password="vinay",Class="Admin"

The attribute is parsed. But when i try to connect with a RADIUS
client, the freeRADIUS server crashes.

What is the correct method of passing attributes from RADIUS server to
the RADIUS Client?

Thanks
Vinay
