I and a few of my test users are having problems with Zimbra returning us to the Zimbra login page. After being logged in for about 2 minutes, the Zimbra login appears and we must log in again.
This did not occur until I changed the default session time limits as admin. I think the default was 2 days! (yes, days!!). I change it to 12 hours. I started having this logout problem so I set it back to 2 days. The problem remains. I tried changin it to 24 hours with no luck.
I did not find anything obviouse to me in /var/log/zimbra.log or /opt/zimbra/tomcat/log/catalina.out.
Perhaps you could suggest a better path for me to explore.
I am running Debian Sarge. Otherwise most things are working well... as well as when I was running FC3. BTW, Thank you again for the Debian version. I MUCH prefer Debian on my servers. (There is a new message quirk that I will post as a seperate message).
