Hi all,

 A new page is available, describing one of the new features of DPM 1.8.10 and its configuration steps.

This is part of the ongoing release of DPM 1.8.10, and will be available when the new packages reach the EPEL repositories.

# 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:

Hi,

the latest release of dmlite (0.7.2) just found its way to EPEL stable, and is available now.

If you are using YAIM, or rely on an older installation that was done with YAIM

(beware, it's deprecated and unmaintained now) you will have to add a line to the main configuration file /etc/dmlite.conf in order to set the log level to 1.

Not doing this will likely print too much information in the logs.

Just paste the following two lines into your /etc/dmlite.conf, AFTER the
