User Managment apps?

[ikellen]

I need a program/script that does more than just the regular adduser program. I need it for a public box I admin. Basically I need the program to:

1. Do all the standard adduser functions
2. Create a public_html directory in their home directory, make the user the owner of the folder with correct permissions.
3. Add them to our pine global address book

And, optionally:

4. Add them to a MySQL or LDAP database if I decide to implement PAM authentication for various things.

Anyone know of a script/program that does this, or could someone write one for me? :D

Thanks

This may help you get started:
Using the Korn shell (http://www.linuxdevcenter.com/pub/a/linux/2002/05/09/uid.html)
I'm assuming you would be able to add a command to invoke a script adding the user to a address book and then a database.
Here's another list of tools:
