OK, I am now coming round to think that there is something wrong with 
Samba 3.6.X after 3.6.3.
Reasons?
I cannot get it show domain users or groups on Samba 3.6.6 running on 
Mint 14, the smb.conf is identical to the one I used on 3.6.3 running on 
Ubuntu 12.04 which works.

I then spent some time downloading and compiling various versions, all 
which failed in the same way.

As I wasn't sure if it was the way that I was compiling samba or not, I 
have installed Opensuse 12.3 and again set up samba with the same 
smb.conf. Opensuse uses version 3.6.12. It fails in exactly the same way 
i.e. getent will not return domain users, only local users.

So, unless anybody is prepared to come forward and announce that they 
are using a version later than 3.6.3, I must suggest that something in 
samba is broken.
