Just in case because I may misunderstand what you are saying...

machine accounts are trust accounts but they aren't a user account and
you can't log in as you would with a user account.

1 - you seem to be making this way too difficult. You should have
appropriate scripts for adding users and adding machine accounts to
domain. Machine accounts should be created on the fly with the right
script. I've never considered fooling with machine accounts in pdbedit
but perhaps there are reasons for doing so.

2 - Suggest that you work through one of the 'By Example' of John's
excellent documentation, perhaps chapter 2...
