About
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("ldap.example.com")) {
// Some credentials
connection.Credential = new NetworkCredential(dn, password);
// Connect to the server
connection.Bind();
// Perform LDAP operations
}
Main Types
The main types provided by this library are:
System.DirectoryServices.Protocols.LdapConnectionSystem.DirectoryServices.Protocols.DirectoryAttributeSystem.DirectoryServices.Protocols.DirectoryOperationSystem.DirectoryServices.Protocols.DirectoryRequestSystem.DirectoryServices.Protocols.DirectoryResponse
