> This is not the best solution from security perspective I agree. The problem is that it doesn't become obvious as long as you use Alvaro' prescription to install the software. When he recommends to start tomcat by the command
sudo /etc/init.d./tomcat start it has all root privileges and everything works fine. The problem arose with starting OM as a service no matter user nobody or kurento. > I would try to find the root cause of such behavior I also agree here. It is probably that LibreOffice uses some resources outside the OM directory that kurento has no right to access. > BTW the issue might be caused by the fact `nobody` user has no $HOME .... I tried that hypothesis too. user kurento has a home directory, which is created during installation at "/var/kurento/". I experimented with changing permissions (group), but in vain the error remains :-( Any suggestions? K. Am Mo., 11.
