"Undefined variable: res" in the PHP log

Recently migrated from sugar. I get this error in my PHP log every 5 minutes.

[Fri Dec 12 18:20:03 2014] [error] [client] PHP Notice: Undefined variable: res in /var/www/sugarcrm/modules/Users/authentication/SugarAuthenticate/SugarAuthenticate.php on line 101

My cron task is executed every minute.

Attached my schedulers screen.

Thanks in advance.

Hi there,

This is a PHP Notice. This is not an error, but simply a notice to inform you of a non-critical issue/bug.

If you search on the forums there are topics on how to hide Notices/Warnings but still log them.
