Optional method in application delegate class to override how to set the password via the change_password action.
You can throw an exception to disallow setting the password entirely.
Example:
function setPassword($password) {
$user = $this->getLoggedInUser();
if ( !$user ){
throw new Exception("Failed to set password because there is no logged in user.");
}
$user->setValue($this->passwordColumn, $password);
$res = $user->save();
if ( PEAR::isError($res) ){
throw new Exception($res->getMessage());
}
return true;
}
