Subject: Fix current session counting
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=089c6e7abc52775a3aca0c77aac610bc80a67624;p=horde.git

Fix current session counting

Instead of trying to manually parse PHP session serialization format,
use the session_decode() function to do the heavy lifting for us. We
need to do some session gymnastics to make this work properly
(session_decode() will overwrite the current session data), but it
works.
