There are two ways that I've done this:

1) keep a "stub" for each machine, overwrite /etc/passwd with it, and
   append your custom entries then (you can also have a marker in the
   regular /etc/passwd and edit it in place).  This can be done
   entirely within cfengine.

2) cfperl (http://lifelogs.com/cfperl) has specific functionality to
   add/delete/change users with the user{add,del,mod} utilities; I
   wrote that functionality precisely because I needed what you
   describe above.

You could also use a network directory service such as LDAP or NIS,
but I assume you have a reason for locally complete /etc/passwd files.
