Another question in addition to George’s:
Look in the fogsettings file: cat /opt/fog/.fogsettings and look for the field called username. What is it set to?This username is the only account that FOG will set the password for. The default is fog.
Generally, users of FOG are quite notorious for setting up the OS with an account called ‘fog’ even though every relevant wiki article and every thread on the topic advises against it. Don’t know why really, I guess the universe wants it that way.
