I've used samba and AD together. I just don't know if:<br>
A) anybody had just made something like this work with wins servers and lmhosts/hosts (it didn't the other day in limited testing)<br>

This largely depends on business requirements---of course, given unlimited time, anything is possible. There is enough implemented in Samba 4.x that it is possible to achieve Microsoft-less servers (as long as you don't have requirements which depend on *other* Microsoft components, such as IIS or any of the Microsoft platform-specific proprietary applications which will run on neither Wine nor Mono).<br>
<br>
Bird's eye view:<br>
<br>
* Migrating from an existing AD infrastructure to Samba 4 is<br>
relatively easy, since it can replicate back and forth. I need to<br>
do testing with newer versions of Windows, but I'm lacking in<br>
licenses on those. I can say that it's really easy to migrate from<br>
Win2k and Win2k3 to Samba 4. It should be relatively easy to<br>
migrate from 2k8 to Samba 4. I cannot say anything about 2k12<br>
because they changed several things, but it should be at least possible.<br>
* You'll need to test, test, test, test!<br>
* If you have _applications_ which run on the Windows Server (e.g., if<br>
the Windows Server is providing more than infrastructure services),<br>
this can be a problem. Some applications can be migrated to run on<br>
a Linux server using Wine or Mono. (Older native-code applications<br>
can typically be run under Wine; <a href="http://ASP.NET" target="_blank">ASP.NET</a> or applications which rely<br>
on the CLR will require Mono.) Each application must be<br>
*thoroughly* tested by its actual end-users to ensure that all<br>
functionality used in production is tested.<br>
<br>
Permissions can sometimes be an issue, but once you have the initial setup there complete (you'll need to internalize an understanding of Windows ACL --> POSIX ACL mapping), you'll be fine.<br>
<br>
There is a module for Samba now, too, that will use btrfs for implementing things like volume shadow copy service and so forth. I have not played with this yet, however I plan to do so (hopefully) soon.<br>
