[Samba] Auto-Create Directory

[Ray Holtz]

I have a samba server set so that each user in a windows 2003 
active directory can have their own personal, private share.  I 
would like to know how to set up Samba so that their directory 
is created automatically, rather than me creating 1300 
directories on the linux server.  

I cannot use pam_mkhomedir.so because 'security = ads' in 
smb.conf and 'encryption = yes' must be there.  I thought about 
making a script to run in preexec everytime, but would that take 
up a lot of CPU cycles?  This is for a highschool, so every hour 
many, many students will all be logging on at the same time.  Is 
there another way to have samba create a home directory for a 
user automatically?

Thanks,
Ray
