Webadmin-reports SSO doesn't work. It shows a reports login page.
Not sure how to test this, when I don't see any "Show Report" button.
SSO is still broken due to other bugs. Adding depends on. This should be available for testing for local installation in the next release.
I just tested it and it worked. Is it supposed to?
Yes. This should be fixed.
oVirt 3.5 has been released and should include the fix for this issue.
