Creating the users home directory on Unix is easy, just add:

session    required   pam_mkhomedir.so skel=/etc/skel/ umask=0022

to the end of '/etc/pam.d/common-session'

When the user logs in, their home directory will be created on the fly.
This is on debian, red-hat has something similar 'oddjob-mkhomedir' 

Or you could use pam_script to run a script the first time a user logs
