| Platform SDK: Active Directory, ADSI, and Directory Services |
ADSI SDK ships with several directory providers, namely, LDAP, WinNT, NDS, and NWCOMPAT. Different providers may choose to implement or not to implement an interface as discussed in this chapter. Of the implemented interfaces, different providers may offer different support mechanism of the properties and methods. Understanding of such provider dependency will help you use the system-supplied providers more effectively. For the information on such provider dependency, see the ADSI System Providers section of this documentation. If you use a third-party provider, consult the documentation supplied by the provider writer.
