I have a security role, say "x". X has read privileges over a,b & c entities, since read privileges are present the entities are visible in advanced find.
This is expected behavior, although the security role "X" doesn't have read privileges over Case, Account & other oob entities but still user with just "X" security role can see all these entities in advanced find!
How can this be restricted? Or is there any specific reason that these entities are by default shown for every role in CRM.
