Hi Daniel and thanks for the explanation.

I want s4 on one box and s3 on another. (I can't see a way of having 2 
smb.conf on the same physical box, so we separate them.)

Currently I'm administering all this using scripts from the s4 DC under 
Linux:

It works fine but the ntvfs fileserver that comes with s4 is rather 
limited. I want to serve files using the s3 fileserver which supports 
the Posix options I need. That will be on another box or VM.

Yes

Yep. I can do that. I already have Linux clients joined to the domain. 
But simply to set the realm and so they can get a keytab using net ads 
keytab create. Nothing else. It's the [global] section on the s3 
fileserver's smb.conf I can't work out!

This is the bit I'm missing. Is this a line in smb.conf on the s3 box?

Those would be everything I have at the moment in the s4 smb.conf except 
the netlogion and sysvol shares? then remove those shares from the s4 
smb.conf?
