There is a lot of good information scattered around this thread for connecting this plugin to Active Directory. In the interest of making things a bit more clear, here are the additional steps required for connecting to Active Directory:

Active Directory:
You need a user to query Active Directory

Firewall:
Don't forget to open firewall ports for authentication if you are working with a DMZ or the like.

LDAP Authentication Settings in vBulletin:
Anonymous Bind: No
Bind DN: <Domain>\<Username>
Naming Attribute: sAMAccountName
Search Base DN: OU=<Whatever>,DC=<your_domain>,DC=<your_domain_tld >
LDAP Attributes: fullName, mail, sAMAccountName

Some points to keep in mind:
1. This plugin doesn't seem to work if your Search Base DN begins with a DN in AD. You must have your search base begin with an OU. This means that if you have multiple OU's at the top level of AD that contain users, you may have a problem.
2. The Bind DN should be passed in the format shown above.
3. Make sure to download product-ldap_auth-1.5_vb4.xml found in this thread, not the one from Haqa's original post. This version contains patches needed for vBulletin 4.
4. The product-ldap_auth-1.5_vb4.xml code attached to this post has a change so that you do not have to specify your DB name:

$dbuserinfo = $vbulletin->db->query_first_slave("SELECT password FROM ".TABLE_PREFIX."user WHERE username = '$username'");

5. WARNING: If you aren't running vBulletin over SSL, you will be passing your Active Directory usernames and passwords in clear text.

Anything else?

Thanks,

Kirk.
