Well, I have made some progress. After more time spent googling (really, should it be this hard to get a basic question answered), I discovered one must add lines to files in the pam.d directory to automate the /home/domain/username directory creation.
This goes into /etc/pam.d/system-auth:
-------------------------------------------------------------
session required pam_mkhomedir.so skel=/etc/skel umask=0022
Now my problem is I have the directories, but the users cannot log in. This message appears after the creation of the directories: "The system administrator has disabled your account."
Further investigation has so far turned up no solution.

Look for info regarding pam_mount . This will apparently mount the user's Windows network directory. I may go that way myself, if I cannot get this other problem licked.
