Our server was recently upgraded from lenny to squeeze. After an upgrade of ISPconfig to latest version, a few days passed without a hitch. A user set a new password in the controlpanel and that emptied the /etc/passwd and only added that one user. Any idea what may have caused this? I have backup of /etc/passwd so I will go onsite to restore the passwd file ASAP. Is there anyway to have ISPconfig be able to "restore" the file properly?
