[RCU] Problems after a switch from Apache2 to Nginx

Hello,

I've recently switched my webserver from Apache2 to Nginx (I'm running Debian 6). Before I could use Roundcube with just an added /roundcube from any domain on my system.

I've tried to things to get that back: 1.st -> I used a symlink to add /var/lib/roundcube as webmail to the respective web directory. 2.nd -> I used a config in Nginx like that: server { server_name webmail.mydomain.us; root /var/lib/roundcube;

access_log /var/log/nginx/webmail.mydomain.us.access.log; error_log /var/log/nginx/webmail.mydomain.us.error.log debug;

location / { index index.html index.htm index.php; try_files $uri $uri/ /index.php; }

location ~ .php$ { fastcgi_param SCRIPT_FILENAME /var/lib/roundcube$fastcgi_script_name; include /etc/nginx/fastcgi_params; include /etc/nginx/php; } }

Both show me a login page - and I can login successfully (I see new mail an all options) - and then after 1-2 seconds I am kicked back to the login page.

Any ideas what I can change?

Thanks in advance!
