samba - Aug 2002 - add user script going Horribly Wrong (tm)

Hi,

I've tried to set up automated user addition and deletion on our Samba 
server, but something's going wrong. Users appear in /etc/passwd, but not 
in smbpasswd, so people are getting login errors and so on when they try to 
access the share. Have I missed a bit of config that's supposed to tell 
samba to set up smbpasswd's too? (smb.conf included below).

Thanks!
