Same Problem I must say I have been using ISPConfig for some time and have never had a problem until now. I recently did a clean install on a server with Fedora Core 8 and ISPConfig. Today I started seeing some strangeness and found this problem. My /etc/group and /etc/gshadow files are empty except the last entry put in by ISPConfig. All groups including system groups 0-500 were removed. Seems to be a problem someplace.
