I've run into a problem after installing nrpe (plugins for Nagios monitoring). The problem was that the installation edited the /etc/group file (more specific, it removed the "apache" group after the website users).
I've corrected this faulty behavior, but by doing that, I've discovered that Virtualmin/Webmin does not correctly reports witch user is in witch group.
If I look in let's say the apache group, none of the website users are in that group. If I look at a website user, it's reported to be in none of the existing groups. But if I look in the /etc/group file, the users are in the apache group.
I see this behavior at every Virtualmin Pro server we manage.
How can this be?
