why not just create another file with a single layout that accesses your main file as an external data source?
In manage security you can adjust the privilege set to control layout access.
Same thing with record access.
I set the advanced security setup so they can only see the layout I want, sweet.
However in this particular security group I need to lock them into their own "User" record, as it stands right now they can find/scroll through all of the users.
What I tried this weekend was to Find their own record using the field I captured in the first place. Or Omit a group of records based on them not equaling the privilege group. Neither work as I expected them to.
