FreeBSD to authenticate against Active Directory

[Stephen Allen]

Hello,

Is there any up-to-date definitive resource which explains how to get 
FreeBSD (6.2) to authenticate against Active Directory (in my case 
Windows 2003 R2 which includes SFU).  There are a few informative 
articles floating around, but most date back to 2004/2005 and most 
involve the use of Samba and Winbind (I'd like to avoid this if possible).

I don't really know what is possible here, I'm coming from only a basic 
understanding of how things like pam work.  Would I have to configure 
every service separately to use Active Directory or could I tell FreeBSD 
to blindly rely on AD for user authentication?

I read about pam_mkhomedir, so users could have homedirs created 
automatically when they logged in.  Is this possible in FreeBSD?  Would 
I be able to map this automatically to their existing "My Documents" 
folder which is redirected to the network by group policy?

Please feel free to tell me what can/can't be done and if doing so is a 
good/bad thing.  I can explain bits in more detail if needed.

Kind regards,
Steve
