[Samba] Samba as fileserver on Active Directory domain

[Robert LeBlanc]

The changes have not made it into a 3.3.x release yet, 3.3.7 was a security
release, ideally 3.3.8 should have the fix. There were quiet a number of
configuration changes from 3.0.x to 3.3.x in regards to Active Directory,
you may not be able to use you old config without updating some things.
