TYPO3 Core

Hi Simon!

I guess the problem is this (t3lib_userauth, line 772):

    // A user was found
if (is_string($this->auth_timeout_field)) {
    $timeout = intval($user[$this->auth_timeout_field]); // Get timeout-time from usertable
} else {
    $timeout = intval($this->auth_timeout_field); // Get timeout from object
}

The check is with is_string().
Can you try if it works with the setting
$TYPO3_CONF_VARS['BE']['sessionTimeout'] = 86400;

Regards
Markus

Sounds logical indeed. I suggest to replace the is_string check with t3lib_utility_Math::canBeInterpretedAsInteger().
