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 and all activities related to that contact id appears. From this [post][1], this is because CiviCRM Entity does not respect CiviCRM's ACL permission. 

I want to see if it's possible to restrict the case activities that only show up if the user has an existing group relationship to the case records. 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 CiviCRM group and validate it against the civicrm ACL.

For example: User A belongs to Group A (staff group). In the ACL, Group A can view contacts from Group B (the clients). When the user uses the case activities report, they should only be able to search contacts to which they have the ACL access from in Group B (not Group C, D, etc.). 

The challenge is filtering on the activities on the user login's group ID.
