[Samba] Migrate users from old server to new server without moving/copying configuration

[Piers Kittel]

Rowland,

Thank you so much for replying!  I'm not exactly sure of the issues, but 
it includes very slow log-in times (>30 minutes if I move to another 
computer I've not used previously) and the KDC doesn't work.  I've tried 
joining the two servers, but it stopped the new one from working 
entirely, and I had to wipe the server and start again.  I've now spent 
some time and got the new server set up perfect, I'm not really keen on 
joining and killing the new server again, but I could try this again if 
you think this is the best way forward?

Many thanks again!

With kind regards - Piers
