Just a suggestion for a future version regarding system usability. I think it would benefit most users to have a tickbox that allows all hosts to have their AD settings reflect the current credential values in the configuration area on each host, this means that you can still use different credentials for different hosts in the same way you can now but on a more optional basis per host.
The majority of people probably use one account designated for FOG to add all hosts to the domain upon deployment so I think that this would make FOG more manageable.
It’s probably more difficult to implement than it seems but would mean that if the user account that adds the computers to your domain was compromised or has it’s password reset then you can easily update all hosts at once and will not need to do this for each individual group as I’m currently having to do.
This would probably make the system easier to manage in the event of a password or entire account change as mentioned above.
