default vlan for ldap users

Hi, Is there any way to make freeradius assign a vlan to any user that was authenticated using active directory database? Something like, freeradius asks active directory for user authenticity, and if accepted, freeradius forwards always the same tunnel-pvt-group-id to NAS. Thanks, Nuno Reis -- No trees were killed in the sending of this message. However, a large number of electrons have been terribly inconvenienced
