that I miss on most other access rights plugins. If you look for a plugin that allow you to lock specific posts or pages and allow access only for specific user groups, this one is for you.
But, I also experienced some bugs/problems with the redirect function on locked pages. The redirect didn't work for me (redirect to an access applocation form), instead the visitor gets a 404 error page which is not cool. Maybe it's a conflict with other plugins, maybe a bug, we will see.
