Consider this scenario:
The Account-Contact Parental relationship is set to configurable cascading, while sharing is set to Cascade None. The security role for users provides them with user level access to the Account and Contact entity records for all the privileges. An administrator who has the System Administrator role in CRM owns an account and shares it with two users. Both of these users have a custom security role as described above giving them access to their own Account and Contact records. A contact created by one user under Account that is owned by Administrator is by default visible to the other user.
Example:
1. User by name Admin has default System Administrator role in CRM.
2. Alan Jackson and Ben Burton are two users in CRM whose security role gives them access to only their own Account and Contact records for all privileges.
3. Admin has modified the Account-Contact Parental relationship to set to Cascade None for Sharing.
4. Admin creates an Account in CRM named "Account1 by Admin" and shares this Account with Alan Jackson and Ben Burton.
5. Alan opens Account record "Account1 by Admin" in CRM then creates a contact under this Account by clicking on Contacts in left navigation pane, New Contact Button, names this contact as "Alan's contact".
6. Ben logs into CRM, points to Workplace, click Contacts, and changes the view to Active Contacts. Contact "Alan's contact" owned by Alan is visible to Ben even though Ben's security role assigns privileges to his own Contact record.
