I'm a little confused on how custom data ACLs work - specifically, when I give a role access to edit a set of custom data fields that are associated with a contact, like so:
Does this allow that role to edit the custom data belonging to any contact or just their own contact?
If it would allow that role to edit custom data belonging to any contact, how can I lock it down so they can only edit their own data?
My use case is this: I want users to be able to log into the site, update their own information, and only their their own. Nobody else's. Their information is in a profile and custom fields.
