I will tell you why looking in /etc/passwd will not work, Michael has
pointed out that with 'winbind use default domain = yes' in smb.conf,
you only have one user 'fred' and he cannot exist in two places at once.
If you don't have that line in smb.conf, as Jeremy pointed out, you can
have a user called 'fred' in /etc/passwd and another user called 'fred'
in AD, but they would not be the same user.

As for the Apollo computer, I doubt it would have had the spare
capacity to do what you suggest, it was too busy doing everything else.
