[Samba] Domain Functional Level & Schema Replication

:) Its M$ again but 2003 and 2003r2 are just as different as 2008 and 2008r2


Its not the windows domain joining that I am confused about as I am sure that works.
What about the NIS information as the schema seems to change on each version until 2008r2

If samba4 is about interoperability then doesn't it need a consistant NIS schema?
