Hello Alan,

Thank you for your answer.
I may have not understood what you wrote.
I replaced in /etc/raddb/sql/mysql/dialup.conf

sql_user_name = '%{Stripped-User-Name}'
by
sql_user_name = '%{User-Name}'

But my authentication is still rejected

[suffix] No '@' in User-Name = "testuser", looking up realm NULL
[suffix] No such realm "NULL"
++[suffix] returns noop
[eap] No EAP-Message, not doing EAP
++[eap] returns noop
++[files] returns noop
[sql]   expand: %{User-Name} -> testuser
[sql] sql_set_user escaped user --> 'testuser'
rlm_sql (sql): Reserving sql socket id: 4
[sql]   expand:  ->
[sql] Error generating query; rejecting user
rlm_sql (sql): Released sql socket id: 4
++[sql] returns fail
Invalid user: [testuser] (from client localhost port 1812)
Using Post-Auth-Type Reject
# Executing group from file /etc/raddb/sites-enabled/default
+- entering group REJECT {...}
[attr_filter.access_reject]     expand: %{User-Name} -> testuser
attr_filter: Matched entry DEFAULT at line 11
++[attr_filter.access_reject] returns updated
Delaying reject of request 0 for 1 seconds

I would like to have simple logins such as testuser and not testuser at somedomain
