CentOS - Jan 2005 - in CentOS 3.4, mod_auth_ldap ?

I'm coming from FC3 and moving to CentOS 3.4.  I have been using
mod_auth_ldap for some time now with Apache 2.x and authenticating to
my Microsoft ADS without problems, here's my article on how that
worked:

However, I have come to find out that CentOS 3.4 only comes with
mod_authz_ldap and when I did some reading on it, doesn't seem like it
will work with M ADS at all.  Any thoughts on how I can get
mod_auth_ldap (not authz) functional with my CentOS 3.4 and where to
get it??

thanks,

I have mod_authz_ldap working ok.  Here's a .htaccess file:

AuthName        "Authorized Access Only"
AuthType        Basic
AuthzLDAPEngine on
AuthzLDAPServer "serverip:389"
AuthzLDAPBindDN ldap_lookup at domain.com
AuthzLDAPBindPassword Ldap_Lookup_password
AuthzLDAPUserKey sAMAccountName
AuthzLDAPUserBase dc=domain,dc=com
AuthzLDAPUserScope subtree
AuthzLDAPSetAuthorization off
require group CN=GroupName,CN=Users,DC=domain,DC=com
