Really? The debug log shows otherwise

# Executing section authorize from file
/usr/local/etc/raddb/sites-enabled/default
+- entering group authorize {...}
...
++[files] returns noop
...
[pap] WARNING! No "known good" password found for the user.
Authentication may fail because of this.

That means files module did not do anything (i.e. it doesn't find a
line matching the request). From initialization section:

Module: Instantiating module "files" from file
/usr/local/etc/raddb/modules/files
files {
usersfile = "/usr/local/etc/raddb/users"
acctusersfile = "/usr/local/etc/raddb/acct_users"
preproxy_usersfile = "/usr/local/etc/raddb/preproxy_users"
compat = "no"
}

Did you edit the file shown in "usersfile"?

yes, i was edit the "users" file at the shown path

Did you follow the example

yes the example in the file and in the wiki.freeradius.org

there? What does it contain now?

testuser Cleartext-Password := "Test"

I'm try to start with linux, read from freeradius.org
Thank that help me
