I can't but Technet can. There are at least 10 pages of information on LDAP implementation both on Windows 2000 Advanced Server, Active Directory, Exchange Server and further have information articles on troubleshooting. Article Q184212 [how to install and use the LDAP service ]is a good article.
The Article Q184212 does not have enough information about LDAP authentication for Active Directory and installation process for Directory services using LDAP authentication.
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
