Configuring Apache so that it exposes a file names /robots.txt implies these two steps:
Add a line in the config file zlcgdm_dav.conf like the following: # Robots.txt Alias /robots.txt /usr/share/lcgdm-dav/robots.txt
Add a file named /usr/share/lcgdm-dav/robots.txt *readable by the user running the apache daemon with this content:
# Disallow all bots User-agent: * Disallow: /
The current trunk release 0.16 already has this. Pre-existing installations should do the manual thing anyway, as the config files cannot be overwritten.
