I just installed roundcube, but I am having some trouble with the session, it seems it just get's lost somewhere after login.
When a user logs in it goes really really sluggish to the main page and shows the emails (if I get lucky) or sometimes starts loading and suddenly just goes back to the login screen. I'm using it on Debian Squeeze with Apache 2 and Dovecot.
I checked if it maybe was a load problem (because everything loads so slow) but there aren't any indicators there is high cpu usage or not enough memory.
