Hello, we use FreeRadius at a school with about 3000 users and divide them into different groups. Since support requests often come from teachers who cannot enter their login data with correct capitalization, we want to use FreeRadius "case insensitive". At school we basically have 3 different groups. username student : 1234567 (a student's unique ID) username teacher: ABCD username employee: t.surname Some of our teachers try to login with "Abcd" or "abcd". That does not work, because FreeRadius is case sensitive. So far I've been browsing the forums and trying a few possible solutions. This includes the solutions from the following thread: https://lists.freeradius.org/pipermail/freeradius-users/2020-February/097517... 1. Changes in the server configuration authorize { update request { Stripped-User-Name := "%{tolower:%{User-Name}}" } ... everything else ... } 2. Changes in the "files" module key = "%{%{Stripped-User-Name}:-%{tolower:%{User-Name}}}" I can only test the login over the command line on our testserver, because i do not want to disrupt our currently working FreeRadius server including the wifi. All tests performed follow the scheme below. root@bkr-app:~# radtest TEST password 10.11.100.31:1812 10 test123 Sent Access-Request Id 245 from 0.0.0.0:33130 to 10.11.100.31:1812 length 74 User-Name = "TEST" User-Password = "start12K" NAS-IP-Address = 10.11.100.31 NAS-Port = 10 Message-Authenticator = 0x00 Cleartext-Password = "start12K" Received Access-Accept Id 245 from 10.11.100.31:1812 to 0.0.0.0:0 length 55 Reply-Message = "DEBUG: Lehrer VPN" Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "37" root@bkr-app:~# radtest test start12K 10.11.100.31:1812 10 test123 Sent Access-Request Id 73 from 0.0.0.0:45170 to 10.11.100.31:1812 length 74 User-Name = "test" User-Password = "start12K" NAS-IP-Address = 10.11.100.31 NAS-Port = 10 Message-Authenticator = 0x00 Cleartext-Password = "start12K" Received Access-Reject Id 73 from 10.11.100.31:1812 to 0.0.0.0:0 length 46 Reply-Message = "DEBUG: Not found, reject" (0) -: Expected Access-Accept got Access-Reject root@bkr-app:~# Is there a way to use FreeRadius case insensitive so that we can reduce the support requests?
