Hello, How can the same user have logged in to two controllers (Zone Director and Virtual SmartZone) at the same time? FreeRADIUS Version 2.2.3 Virtual Smartzone High Scale: 3.6.0.222 Zone Director ZD3025: 9.12.3.0 build 105 We were migrating the APs from ZD to VSZ, but as the pandemic emerged and everyone is at home now, we stopped the migration and the two controllers are in operation. In the corresponding radacct of each controller, I found the chronological order: Tue Jun 9 09:47:11 2020 Acct-Session-Id = "5EDF8325-2E943C01" Acct-Status-Type = Start Acct-Authentic = RADIUS User-Name = "x" NAS-IP-Address = IP_VSZ NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 802.11b/g/n" Event-Timestamp = "Jun 9 2020 09:40:07 -03" Ruckus-SSID = "Y" Tue Jun 9 09:48:45 2020 User-Name = "x" Acct-Status-Type = Start Acct-Authentic = RADIUS NAS-IP-Address = IP_ZD NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 802.11g/n" Acct-Session-Id = "5C108A3D-0458941E" Acct-Multi-Session-Id = "2ce6cc39d168687d6b0eb2b35edf852cc33a" Ruckus-SSID = "Y" Event-Timestamp = "Jun 9 2020 09:48:45 -03" Tue Jun 9 09:55:40 2020 User-Name = "x" Acct-Status-Type = Stop Acct-Authentic = RADIUS NAS-IP-Address = IP_ZD NAS-Port-Type = Wireless-802.11 NAS-Identifier = "2C-E6-CC-39-D1-68" Connect-Info = "CONNECT 802.11g/n" Acct-Session-Id = "5C108A3D-0458941E" Acct-Multi-Session-Id = "2ce6cc39d168687d6b0eb2b35edf852cc33a" Ruckus-SSID = "Y" Event-Timestamp = "Jun 9 2020 09:55:40 -03" Acct-Terminate-Cause = Idle-Timeout T imestamp = 1591707340 Tue Jun 9 10:08:06 2020 Acct-Session-Id = "5EDF8325-2E943C01" Acct-Multi-Session-Id = "743e2b370028d077146daa375edf8325ba1a" Acct-Link-Count = 1 Acct-Status-Type = Stop Acct-Authentic = RADIUS User-Name = "x" NAS-IP-Address = IP_VSZ NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 802.11b/g/n" Event-Timestamp = "Jun 9 2020 10:01:02 -03" Ruckus-SSID = "X" Att *César Murilo da Silva Júnior* *Téc.
