That's funny, I thought I was the only one. I recently upgraded Apache
to 2.2 and php to 5.3.8 (from 5.2.8) and switched back to 5.2.8 when my
boss found the problem with firefox 3 under linux- he could log on which
was confirmed by the horde.log but after the login the login page was
shown. I solved this by switching to cookies only (with a redirect from
hostname only to the FQDN of the server in Apache).
