Okay I've dug out the issue and had a play but on Intrepid it seems to 
use some new method of authenticating with PAM.  Looks like a good idea 
but I can't find any good documentation on it.

I've enabled LDAP on the SME Server now which I'm hoping will work 
better for what I need.

The problem again is that I can't find any documentation for Intrepid.  
I did find something for Hardy bit that didn't seem to work on Intrepid 
(I ended up breaking sudo with that one!).

Times like this I wish there was a nice GUI which would help me setup 
authentication against the server using LDAP.  I wonder if Likewise will 
do this? (I know it authenticates against Active Directory but I'm not 
actually running AD, just LDAP and a Samba PDC).
