Add a new user or group

Administrators can use the programs /usr/sbin/luseradd, /usr/sbin/luserdel, and /usr/sbin/lusermod to add, delete, and modify users from the directory. There is also a more-friendly(??) program for adding users: /usr/local/bin/adduser-npg, however it requires that the above programs and more be accessible via the PATH environmental variable (root has the appropriate path set up, but neither sudo nor su will use that path).
