Delete local accounts created when logging into Active Directory?

Question

When a user logs into their Mac using their Active Directory credentials, a new local user folder is created that corresponds to their login name. But a new account doesn't show up in the System Preferences Accounts. So how do I go about deleting this local account? Can I simply delete their Users folder?
Thanks.

AD does this with Windows, too. This is because the AD account is not the same as the local account. If you have a user with the username joeuser, and he has a local account named joeuser, he'll have a home directory in that name. If he logs into and AD system with the domain name ADDomain, there will then be an account with a name something like joeuser.ADDOMAIN, which, by definition, is not the same as the account joeuser. On a Windows box, at the same time as the joeuser.ADDOMAIN account is created the joeuser account will have its name changed; if the box's name is joe's_mac, the joeuser account will become joeuser.JOE'S_MAC. This kind of thing will apply only to users who have both local and domain accounts. Users who have only local accounts, such as jilluser, will not have their account name changed. Users who have only domain accounts, such as bobdomain, will not have their account name changed. Users will not notice any difference in the way they log in; they will log into their domain account, and see just what that account has access to, or will log into their local account, and see just what that local account has acces too, depending only on how they set the login box. They will never have to enter joeuser.ADDOMAIN, just joeuser... and the domain name in the proper place.
If you delete the domain account, a new one will be automatically generated as soon as the user logs back in using a domain account. Any data stored in that account will be deleted when you delete the account.
