When loading Zend_Session options via an ini file using the Zend_Session::setOptions() function, the remember_me_seconds setting in the ini file does not change the cookie lifetime. Cookie lifetime does change if the programmer calls Zend_Session::rememberMe(). Zend_Session::rememberMe() internally calls Zend_Session::rememberUntil() to set the cookie lifetime. However, Zend_Session::setOptions() does not call rememberUntil() on the remember_me_seconds option and so the cookie lifetime does not get set. This can be mitigated by using Zend_Session::rememberMe() for this one option.
