Hi Alejandro, thanks very much. Unfortunately in our case only the Outer Identity is included in the Access Accept from FR to the NAS and the NAS in turn requests accounting for the outer ID instead of the inner ID it’s supposed to: Access Accept from FR to NAS: (22) Tue Nov 20 16:51:07 2018: Debug: Sent Access-Accept Id 16 from 131.152.21.102:1812 to 10.33.6.2:47901 length 0 (22) Tue Nov 20 16:51:07 2018: Debug: Tunnel-Type = VLAN (22) Tue Nov 20 16:51:07 2018: Debug: Tunnel-Medium-Type = IEEE-802 (22) Tue Nov 20 16:51:07 2018: Debug: Tunnel-Private-Group-Id = "822" (22) Tue Nov 20 16:51:07 2018: Debug: User-Name := "anonymous@unibas.ch<mailto:anonymous@unibas.ch>" (22) Tue Nov 20 16:51:07 2018: Debug: Chargeable-User-Identity := 0x64323132363438353066316665356233653031353835333765373737343136613730366530343436 (22) Tue Nov 20 16:51:07 2018: Debug: MS-MPPE-Recv-Key = 0x36785f7c835847b8f8b19bd771144a9b1484e34ad90f094484152b53ab88a5ee (22) Tue Nov 20 16:51:07 2018: Debug: MS-MPPE-Send-Key = 0x04d8aef1be7ce80b6f7eb382d782d6227924a40379be4e9725254878108bd96d (22) Tue Nov 20 16:51:07 2018: Debug: EAP-Message = 0x030b0004 (22) Tue Nov 20 16:51:07 2018: Debug: Message-Authenticator = 0x00000000000000000000000000 Accounting Request from NAS to FR Port 1813 (Accounting Server): (11) Tue Nov 20 11:23:28 2018: Debug: Received Accounting-Request Id 247 from 10.33.6.2:47901 to 131.152.21.102:1813 length 551 (11) Tue Nov 20 11:23:28 2018: Debug: User-Name = "anonymous@unibas.ch<mailto:anonymous@unibas.ch>" (11) Tue Nov 20 11:23:28 2018: Debug: Chargeable-User-Identity = 0x64323132363438353066316665356233653031353835333765373737343136613730366530343436 (11) Tue Nov 20 11:23:28 2018: Debug: NAS-Port = 8 (11) Tue Nov 20 11:23:28 2018: Debug: NAS-IP-Address = 10.33.6.2 (11) Tue Nov 20 11:23:28 2018: Debug: Framed-IP-Address = 10.172.40.114 It’s weird cause it used to work fine for a long time and we assume something has change in FR 3.x over 2.x regarding this behavior but don’t know for sure.

That made that some NAS were taking the outer one since it appeared first. We pushed a fix upstream https://github.com/FreeRADIUS/freeradius-server/pull/2297/commits/ad3791dc84... If your issue is the same, you just need to backport that change to your "default" site and check whether it fixes it. Best regards, Alejandro El 19/11/18 a las 16:05, Thorsten Fritsch escribió:
Hi guys,
we have recently upgraded our FreeRadius to release 3.0.17 and are now facing the issue that the accounting logs seem to contain the username provided in the anonymous (outer) identity field instead of the username used for the inner tunnel. This makes it hard to identify our eduroam users (user tracking).
Has something changed in FreeRadius 3.x regarding thise behavior ? In my understanding the Radius server should provide the inner tunnel username to the NAS (in our case Cisco WLAN Controller) by parameter use_tunneled_reply = yes in the eap file under /mods-enabled which the NAS can then in turn provide to the Accounting server is that correct ? We have set this setting to yes in our config:
ttls { tls = tls-common default_eap_type = mschapv2 copy_request_to_tunnel = yes use_tunneled_reply = yes virtual_server = "eduroam-inner-tunnel" }
peap { tls = tls-common default_eap_type = mschapv2 copy_request_to_tunnel = yes use_tunneled_reply = yes virtual_server = "eduroam-inner-tunnel" }
Thanks for your help.
Cheers, Thorsten
