Update: now I can't login to the ikiwiki.info site anymore, getting
the same errors as on the git-annex site.
+Update2: it seems this is specific to the HTTP/HTTPS switch. If I use HTTPS, things work fine, but not with plain HTTP. So I'm moving this to the branchable wiki, as I am not having that problem on other ikiwiki sites. Maybe the bug specific to ikiwiki is the lack of clarity in figuring out wth is going on here... See <http://www.branchable.com/bugs/login_failures_without_https>
