I am running Fedora FC4 with FR 1.0.4 (yum updated) with MySQL 4.1.12. I am trying to use in rad_reply table for Session-Timeout with the following value: `%{expr: %{sql:SELECT IF(NOW() <= user_stoptime, (TIME_TO_SEC(TIMEDIFF(user_stoptime, IF(NOW() >= user_starttime, now(), DATE_SUB(user_stoptime, INTERVAL 1 SECOND))))), 1) FROM phs_user WHERE user_username='%{User-Name}'}}` This doesn't work as the Session-Timeout value is not assigned. The sql statement alone works fine and returns the correct value. I then tried to get a simple expression up and running in rad_reply: Attr Op Value Session-Timeout = `%{expr:3600 - 300}` No success. In debug mode I can see that the expr module is loaded: Module: Loaded expr Module: Instantiated expr (expr) I then compiled and installed 1.0.5 ... with the same result. Then I created a user in the ./raddb/users file and assigned the Session-Timeout with above SQL statement and it works fine. What is wrong getting the Session-Timeout from the rad_reply table? When I assign a fixed value, e.g. 3500 in the sql row, it works fine. Anything with MySQL collation maybe? I changed it to different languages ... no success. This is the debug output when I use the users file, when using sql, I do not get this.
