[Samba] ldap & winbind

[colinjenkins]

For a few weeks now, I have been attempting to set up a linux box to 
authenticate from a win2003 ldap server

All the article Iv'e read mention winbind, but it has been removed from 
our network.
I'm only running 1 linux (mandrake) box as a web server, and just want 
to have all authentication done from ADS.
is this possible without winbind?
any other pointers?
