I was having the same issue (redirect works with default URL, not with permalinks).
I found this older post describing a code change, but couldn’t apply it as-is because it refers to an older version of UAM.
However, below change in UserAccessManager.class.php, public function redirect does solve the issue for me:
} elseif (isset($oPageParams->query_vars['name'])) {
// frene7ik 20130516
//$oObject = get_page_by_title($oPageParams->query_vars['name'], OBJECT, 'post');
$oObject = get_page_by_path($oPageParams->query_vars['name'], OBJECT, 'post');
if ($oObject !== null) {
$oObjectType = $oObject->post_type;
$iObjectId = $oObject->ID;
}
