Don't understand why you think the 'guest' user is 'properly
restricted', it isn't a standard Unix user, so you must have created
it, so it is as restricted as you made it, but it is a member of the
'users' group, so it will have all the permissions of that group.

Did you know that a guest share has another name, it is 'A wide open
share', the only way to get a guest share to work is to 'chmod 2775' on
the share, if you want security, then do not use a guest share.
