UnPriv User - Attachment Custom Fields


We have some custom fields that are for attachments…when the un-priv
user (in self service) clicks the link, it takes them to the default
self service page.

Can anyone tell me what permissions I need to change to allow the user
to get to /Downloads/CustomFieldValue/dhandler?

I have looked at Linux file permissions and am not sure where else to
look. I don’t see anything in Apache, I am sure its something silly
that I am just not thinking of.

Please advise,
