Yep. Thanks for the link.
Looking for the following to start with but I am not real familiar with OSX so I am not sure what else there should be.
- Add new user (and specify a password)
- Remove a user
- Add or remove an existing user to the admin roll.
I think the admin roll can be managed via the d or a switch for dseditgroup:
dseditgroup -o edit -n . -d {parameter “UserName” of action} -t user admin
