Dear people, I have a Freeradius server that authenticate users against an AD in order to access the WiFi network: Once a user authenticates OK and access the WiFi network, in the debug log of Freeradius I notice that this user has several access requests at the same time he is using the WiFi correctly. The access request frames are as the shown below: rad_recv: Access-Request packet from host 192.168.10.1 port 32768, id=103, length=432 User-Name = "jsmith" Chargeable-User-Identity = "" Location-Capable = Civix-Location Calling-Station-Id = "80:ab:17:46:69:10" Called-Station-Id = "6c:99:89:8b:62:50:Employees" NAS-Port = 13 Cisco-AVPair = "audit-session-id=ac1f0c620001129d5bd059a8" Acct-Session-Id = "5bd059a8/80:ad:16:46:69:10/117467" Cisco-AVPair = "mDNS=true" NAS-IP-Address = 192.168.10.1 NAS-Identifier = "CC-803" Airespace-Wlan-Id = 8 Service-Type = Framed-User Framed-MTU = 1300 NAS-Port-Type = Wireless-802.11 Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "803" EAP-Message = 0x0207006b1900170301006097b83712638612527a05475ecd25d67e6076490aee95d35c489925635aee89c40643f7792122452628ac3c6deb27afd73a619069eab529f5afcc4646fa17195991294d33614f549480f045e3a0aba117ff7c4182bdfdbd935055c2577f056d01 State = 0x413cfeec443be7e0d7f6ff4a2526d7aa Message-Authenticator = 0xc54014a6929ff04d4e13b6a8be7b79ad Why is this behaviour? Because I thougth the access requests are used only when the user is going to authenticate and never. Thanks a lot, regards !!!
