In theory, yes it should be entirely possible. My user's authenticate
against a Novell eDirectory Netware Server via LDAP. However, I've not
heard any reports of someone successfully configuring Windows 2003 AD LDAP
and Courier. AD is a somewhat different beast then OpenLDAP or even
eDirectory. The first error your recieving here seems to be an
authentication failure. Did you enter an admin account in
/etc/authlib/authldaprc LDAP_BINDDN and LDAP_BINDPW? You will need to
specify the full context for BINDDN, it should look something like:

CN=Jay Jamieson, OU=Worcester,DC=cp,DC=com

also, I don't believe AD will search sub organizational units by default
(i.e. search down the tree) so you will need to make sure LDAP_BASEDN is
set to the exact area where your users exist. I am not sure if it's
possible to specify multiple ou's for LDAP_BASEDN, Sam may know.

One thing that may help is to use a LDAP utility program to browse your
tree and get a better understanding of how your AD looks from the LDAP
side. I've used Softerra's free LDAP Browser in the past and found it to
be useful:
