Hello Andrew, hello Scott,
Thanks for your answer.

I’ve already look the Apple source code for their Samba version, and it use the local directory service to run. So, the problem with that solution is we need to install it on a OS X, in place of SMBX, this is not a really update proof solution.
That's why I look to make a UNIX box on a side to make an adapter to translate AD to OD.

Thanks a lot for the indication about pdb_ldap and auth_winbind, that’s what I looking for. I will study that.
A step forward, how do you register backend extension in Samba? On CentOS I’ve seen that backend for idmap are simple .so file on the disk. It’s the same for pdb and auth?

It depends of the Samba architecture. At a time in Samba, you should got the new password in clear text to be able to hash it in different ways? So it should be possible some how to forward it to the Apple PasswordService.

That’s not a acceptable way to go for me and my clients. We use OS X Server and OpenDirectory as a directory service because it’s lowcost, really easy to use and robust, created on really simple standard and powerful. It don’t have to be so complex like the AD DC. And my client are manly OS X based. For example, the one for who I look here is a small business with 200 Macs and 2 TS server. Go on the AD complexity for only 2 TS server isn’t a good way to go…
