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 sudo won't use that path).
