What it means is, you need to add/change the users and groups and set
permissions to meet your requirements.

This is up to you, by doing what Louis is suggesting, is security
through obscurity. It means that anybody trying to get into your system
has to know (or obtain by whatever means) not only the password, they
also have to know the username to go with it.
As for removing the accounts, you need to decide just who has access
and how much access they have, this may mean removing, altering or
adding accounts.

If the windows machine that ADUC is running on is joined to the domain,
it normally allows you to set the domain on the 'Unix Attributes' tab
and setting this, fills in all the other boxes (uidNumber etc)
