Trusting between Confluence and JIRA : does not work on portlets

we have finally upgraded both Confluence and JIRA to latest version to test the trusing between Confluence and JIRA.
It is meant to work on :

• JIRA Issues macro
• JIRA Portlet macro

I have tested that it works with JIRA Issues but it does not work on JIRA portlet. I have to specify users and password to let a portlet set in JIRA on my account (same user details) to be shown.
