I have created an apex application and I have some end users which should log in to the application and use it, I realized that there is not any change password or reset password option for end users !!! How can I add it to login page ?? I have done that based on this link, but the problem is when any username is not entered, it goes to the change password page and after presseing the change password button an internal error box appears !
