[horde] Horde - Sessions

[Michael Post]

Hello,

i have a problem with my horde installation and sessions.
Session will be created in tmp dir on my server after successful login 
per imp authentication.
After login i see my last visit: Never

Ok. I log out and relogin.

Last visit: Never

When i add content to the dashboard i do not get any content after a 
relogin.

Do you have any idea what is the problem or where i can search for it?

Thanks for support,

Michael
