System.DirectoryServices.Protocols provides a managed implementation of Lightweight Directory Access Protocol (LDAP) version 3 and Directory Services Markup Language (DSML) version 2.0 (V2) standards.

It primarily uses the LdapConnection type for interacting with LDAP servers, using system native libraries to establish TCP/IP or UDP LDAP connections. Supports both Windows and Unix, but certain features, such as setting client or server certificate options, are not available on Unix.

Key Features

  • Managed implementation of LDAP v3 and DSML V2 standards.

How to Use

Using the LdapConnection type, you can establish connections to LDAP servers and issue requests.

Here is a simple example:

using System.DirectoryServices.Protocols;

// Create a new LdapConnection instance using the server URL.
using (LdapConnection connection = new LdapConnection("")) {

    // Some credentials
    connection.Credential = new NetworkCredential(dn, password);

    // Connect to the server

    // Perform LDAP operations

Main Types

The main types provided by this library are:

  • System.DirectoryServices.Protocols.LdapConnection
  • System.DirectoryServices.Protocols.DirectoryAttribute
  • System.DirectoryServices.Protocols.DirectoryOperation
  • System.DirectoryServices.Protocols.DirectoryRequest
  • System.DirectoryServices.Protocols.DirectoryResponse
