Well, hard to say with no details of your configuration ("followed everything"
might mean something to you, but for the rest of us it's "what everything?").
I've had some trouble getting LDAP authenticate against AD some time
ago, that I
resolved (no samba, no anything, just LDAP authenticating users). It
are going couple of steps further then me.
Anyhow, what version of AD you have? 2000 and 2003 are a bit different, and
there are steps that need to be done with 2000 that are not needed with
get the Kerberos stuff working.
For what you are trying to do, you'll probably need to configure both Kerberos
(to get authentication going) and LDAP (to get user lists) correctly. This
usually means creating principals for Unix services by hand, and coping keytab
files back to the Unix side. Do you have all schemas on your AD that are
needed for Unix accounts? Can you use ldapsearch to bind to AD and
There's an excellent Microsoft document titled "Windows Security and Directory
Services for UNIX". You can download it for free as PDF from Microsoft web
site. I'd higly recommend you get it. It has almost all you need to know
about configuring AD and Linux side to play nicely with each other. Skip "for
IT managers" parts, and go to technical sections.
