The "Restrict to articles with labels" option doesn't restrict the customer portal from suggesting KB's other than those with the nominated Label

Summary

Currently we have the "Restrict to articles with labels", where you can specify the label for a request. When a customer is filling the summary for a request, SD will search the knowledge base for similar content from confluence pages with that label.

However, the customer portal search does not apply these labels when searching and displays knowledge base articles that would not appear as suggestions under any of the request types in that portal/project.

Environment

Reproduced with JIRA 7.0.10 and Service Desk 3.0.10

Steps to Reproduce

1. Create a page in confluence Eg: name Page One
2. Label it as "mylabel"
3. Create a second page in confluence Eg: name Page Two
4. Go to the Service Desk "Confluence KB" page of a project
5. For all request types add the label "mylabel" under Restrict to articles with labels
6. Login as customer from the portal
7. In the individual portal for this project search for Page.
8. Under the search bar the KB suggestions should show up

Expected Results

Should only show PageOne as the request types in this project are restricted to mylabel

Actual Results

Suggests all KB's

Notes

This is reproducible in JIRA 6.4.13 and Service Desk 2.5.9

Workaround

Use a specific Confluence space for the knowledge base that only contains pages you wish to share with Service Desk users. Or use another group, except jira-servicedesk-users, to restrict page access in Confluence.
