Enabling Directory Index is buggy
Based on a lot of forum reading I managed to figure the combination which is required to make directory index work in apache

- Server config, web, security -> Medium
- PHP enabled for website
- Not sure if it is needed at this moment, but I have additional directives in the website
<Directory "/var/www/clients/client19/web28/web"> AllowOverride All Options +Indexes Order Allow,Deny Allow from all
After all, only a combination of 1 and 2 allows for using Indexes option. At least #2 (closed) is definitely a bug, #1 (closed) is more like unobvious behavior.
