[Samba] samba3 FreeBSD pdc

[Dave]

Hello,
    Most of the docs i've seen for implementing samba3 as a pdc are for 
Linux. And for a most part they work with FreeBSD. I've not got the box 
production yet, i have several questions and was wondering if anyone used 
samba3 on fbsd as a pdc? If so i'd appreciate hearing from you. I want to 
set up single sign-on authentication, and password changing with the fbsd 
system. So that a user can ssh in to the box change the password it's 
reflected everywhere or the user does it from windows. I am not getting the 
passwd chat string right. And some of the scripts add machine to group, 
scripts i haven't been able to get them working with fbsd, this is version 
6.2 btw, i don't think i'm going to have the issue of not being able to add 
a $ in the username.
Thanks.
Dave.
