I have a Drupal 7 Views that produces a case activities report. It has columns like scheduled activity date, contact id, notes, etc. The user can search by contact id. I like to restrict the page access, either: (1) the contacts that show up should only appear if the user belongs to Group A Users. or (2) the page should not be accessible at all if the user does not belong to Group A Users.

I think I'm close. I have the Group ID as a relationship (access control: clients). I just can't get Views to check the login user's group and validate it against the civicrm ACL.
