Hello,
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}}}"
That should work. IF all of the users and passwords are in the "users" file. So... where are the users? LDAP? SQL? Active Directory? You haven't said.
Our users are logging in via LDAP. I´ve seen that the file "ldap" has some filter rules. # filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" filter = "(uid=%{mschap:User-Name:-%%{User-Name}})" I´ve activated the first one without mschap and the variations with tolower -> filter = "(uid=%{mschap:User-Name:-%{tolower:%{User-Name}}})"
Why are you wasting your time looking at the output of radtest? ALL of the documentation says to run the server in debug mode.
Read the documentation and follow it. You get a link to the documentation when you join the list:
After starting freeradius in the debug mode i saw a configuration file that contains the attribute case_sensitive. That file "is called radutmp". But from my understanding of the file description that file is only for some sort of logging. To see who is logged in and some other stuff. After testing the the login while in debug mode, the error message stays the same. I´ve added the debug messages. You can see that the username is affected from the tolower in the server configuration in the authorize section. The problem lies with the ldap. The uid of the user stays as the normal input and seems not to be affected by the tolower string. LDAP somehow has no problem with it, because an user object is found with the right name. But it somehow can´t change the username in the request while searching the groups.
