Help, syncing Active Directory users and groups

[nullman]

Hello,

I was able to get NTLM authentication and NTLM pass-through working following the Wiki. However, I haven't been able to get my Acitive Directory users and groups to sync via LDAP.

I don't get any errors when Alfresco starts, but I do see this when I enable debug for LDAP:

14:34:20,446 DEBUG [authentication.ldap.LDAPGroupExportSource] Found 0
14:34:20,446 DEBUG [authentication.ldap.LDAPGroupExportSource] Top 0
14:34:20,446 DEBUG [authentication.ldap.LDAPGroupExportSource] Secondary 0

Does this mean my LDAP connection is working, but I am searching AD incorrectly?

Our Setup: Windows 2003, Community 1.3.0 bundle (Tomcat)

(Edit: This post was edited after learning more about how to configure LDAP/AD)
