Hi Folk, I have activated attr_filter for a realm (dr4.cnrs.fr) and want users from that realm to have 2 possible values of VLANs (VISITEUR or SIRC) Here is my attr_file: dr4.cnrs.fr Service-Type == Login-User, Framed-IP-Address == 255.255.255.254, Framed-MTU >= 576, Proxy-State =* ANY, Reply-Message =* ANY, EAP-Message =* ANY, Message-Authenticator =* ANY, State =* ANY, Session-Timeout <= 28800, Idle-Timeout <= 600, Port-Limit <= 2, Proxy-State =* ANY, MS-MPPE-Recv-Key =* ANY, MS-MPPE-Send-Key =* ANY, User-Name =* ANY, Called-Station-Id =* ANY, Calling-Station-Id =* ANY, NAS-Port-Type =* ANY, NAS-Port =* ANY, NAS-IP-Address =* ANY, NAS-Identifier =* ANY, Framed-Filter-ID =* ANY, Tunnel-Type == VLAN, # Tunnel-Type =* ANY, Tunnel-Medium-Type == IEEE-802, # Tunnel-Medium-Type =* ANY, Trapeze-VLAN-Name == VISITEUR, Trapeze-VLAN-Name == SIRC, # Trapeze-VLAN-Name =* ANY, Tunnel-Private-Group-Id == VISITEUR, Tunnel-Private-Group-Id == SIRC # Tunnel-Private-Group-Id =* ANY When i test the connexion with my account (my attribute Tunnel-Private-Group-Id = Trapeze-VLAN-Name = VISITEUR), the authentification is OK but radius server do not send this attribute to the NAS: they are filtered and they should not. When I set those attributes to * ANY, every thing works well. I don't understand this behaviour.
