This is a very simple module that provides a CTools access plugin for using the access rules of another path. It does nothing without the CTools module.
When creating a custom page with Page Manager (for example, a Panels page), this module adds the 'Access to another path' access plugin in the Access tab. You may use it to mirror the access rules used by another path. For example, you might set up a custom search page, and use the access rules for the default Drupal search page, 'search'.
