This is achieved by making those users members of a group, and then giving ownership of the ibay to that group, ie write=group read=group, see the setting choices in the ibay configuration.
In this case (local file sharing) do not set the ibay to require a password.
...
I don't think this is what he is trying to achieve. I think he wants to apply user-level authentication to the HTTP part of the e-bay.
From my knowledge of SME 6.x only (I don't know if SME 7 has changed in this area) it is simply not possible to do that through the admin pages.
Authentication can be added to an i-bay (the HTTP part) using .htaccess and .htpasswd files, but those passwords would be hard-coded into those files - they would not automatically pick up the current user password, or allow authentication against a group of users.
Applying a password to an i-bay http access means all users accessing that i-bay would need to share that password. You could not be able to simply add and remove users from that group without creating a new password and sharing it will all the current users with permission to use that i-bay through their browser.
Incidently, this is a common requirement, especially where access to an i-bay through WEBDAV is required. For example, users sharing an i-bay over the Web to hold their i-cal calendar files. Being able to restrict access to that i-bay (perhaps even allowing read-only access to everyone, but write access only to individuals able to update their calendars), and the ability to ensure people log on as themselves, is very useful. I tend to customise templates to support this, and will be doing so again when I install my first SME7 today

Protecting an i-bay on the Web with a single, shared, password is fine if the password is changed regularly, but is very limiting. Allowing access to an i-bay over the Web using the built-in SME user authentication out of the box, would be very cool.
