Hi Geza
Thanks so much.

Yes, we had both the Ubuntu 3.6 and the 4.0 beta on the same test box. 
Our m$ guy had had a go with S4 and obviously succeeded without telling 
me. To be fair, I should add that it was upon my encouragement.

Conclusion. Samba4 is so easy to install that even a windoze admin can 
do it;-)

Cheers,
Steve
