Freeradius and vlan assignment

Hello!

I am working on implementing *freeradius* with a cisco 3750 switch
connected to *freeradius*, which then talks to AD.  (The linux box is on the

AD domain)

Anyway, we try to make vlan assignment by using the 'users' file .

We create a user named 'test' on my AD server , and we created this section
in the file users :

test    Auth-Type := MS-CHAP
        Tunnel-Type = 13,
        Tunnel-Medium-Type = 6,
        Tunnel-Private-Group-Id = 2

The user is correctly authenticated by AD , but he is put in the default
vlan ( id 1 ) and not in the vlan defined in the file 'users' ( id 2 ) .

By the way, readind the radiusd output , i think that freeradius does not
read my users file...i didn't see int he log anything about the Tunnel-Type
or Tunnel-Private-Group-Id informations....

Anyone have any thoughts?

Regards

Bruno
