Contact own account access denied

Using RedHen with Open Outreach my contacts with viewer roles cannot access their own accounts, although permissions are set for them to. No RedHen users can view any accounts unless the 'Access RedHen Contacts' permission is set, while the Access Own RedHen Contact does nothing.

The RedHen Administrative Menu displays no option, and direct access to the contact node views display 'Permission Denied'. No other errors are given.
