I hope so, I am at the moment at the same stage. Locally my Samba4  
seems to work (under FreeBSD and ZFS which had its own challenges)

So next step is testing replication. It's on my plan for the next days.

4.0 had a FreeBSD specific problem with replication but it seems to be  
fixed since 4.05 (BUG 9656: Work around FreeBSD's getaddrinfo()  
underscore issue)

So I am looking forward!

I have the question too. Replication is a "black box" for me so your  
guess is good as mine;-)

I will keep you informed if I see issues.

As a sidenote: How difficult are updates? The FreeBSD port system is a  
bit behind so I wonder whether there are major obstacles when  
upgrading to a newer 4.1 version in the future.
