Problem To Authentication In Yii 1.1.14 Version

I’m using Yii 1.1.14 version, but in this version, I can’t use “Remember Me Next time” in default Yii login form. When I Pass The “Duration” time in the $duration variable in function Yii::app()->user->login($this->_identity,$duration); under Model “LoginForm.php”. It show an Error that is “Cannot open source device”

I also tried with username+password demo+demo using default useridentity.php, It shows the same error message.

Can Anyone Help me why It is showing this error message? and It’s Solution.

Dear Jaimin MosLake,

in main.php under config folder, the default value is True, like allowAutoLogin=> true, But it is showing error when i check in "Remember in Next Time".

This error is showing only on Yii 1.1.14 version.
