Joomla SEF with nginx

Hi.
I've nginx ISPConfig. For a single host I have different joomla installations for which I'd like to enable SEF. SEF is enabled by default on latest versions, but it won't work with ISPConfig out of the box. The urls enabled are like

web.sit.e/index.php/slug1
So that should work without special rules. Unfortunately it seems nginx is not trying index.php and returns 404. I cannot figure out why, anyone has ideas?
thanks

 

Solved with this

Code:

# for joomla installations in subdir
location ~ ^/(?<anyfolder>[a-z\-]+\/) {
   try_files $uri $uri/ /${anyfolder}index.php?$args;
}

# if the above doesn't match (missing traling /) handling for joomla site in root
location / {
   try_files $uri $uri/ /index.php?$args;
}
