If a customer is viewing a Confluence article from the JSM portal and clicks on a link something like the 'edit' button on an attached PDF file...

They get redirected to an Atlassian Confluence log in page.

It will allow them to create an account, but after logging in with that account it says they don't have access to our Confluence instance.
If they click on the PDF icon they are able to download the PDF.
Why is there an 'Edit' button available for the customer? Why does this go to a log in page? Should it just go to an error page saying they don't have access?
I think this will really confuse our customers.
