Summary:

With the option "All active users and all customers (they don't need a Confluence license)" for Knowledge Base integration, customers still not able to view the KB articles.

Steps to Reproduce:

1. Create a Confluence Space and a user that is allowed to view and create page in the Space
2. Configure the Application link as mentioned in Serving Customers with a knowledge base
3. Use the "Execute As" configuration instead on Confluence Oauth Incoming Authentication instead of the Impersonation and use the previous created user.
4. Log out from Confluence and linked the previously created Confluence Space on a service desk project with configuration "All active users and all customers (they don't need a Confluence license)" selected
5. Login as Customer and search for an existing KB page.
6. Click on the search result.

Expected Result:

• As Customer, I would be able to view the Article.

Actual Result:

• Still being asked to login to Confluence.

Notes:

• JIRA 7.1.0, JSD 3.1.0 and Confluence 5.9.3 are used for this test
