Using LDAP API

You can use LDAP API (functions like ldap_open and ldap_bind_s) to communicate with Windows 2000 Active Directory. You can specify the port number, as well as provide security credentials for a server. I have a small code sample (App/LdapBind) described in the LDAP Security section of the Appendix that basically shows how to bind to directory objects using LDAP API. Notice that a detailed description of LDAP API is not in the scope of this book. Here I just want to point out that this is definitely possible and you can use it if you like.
