3.1 Binding an Entry to an LDAP Server

The bind operation allows the entry to authenticate to the server. An entry in a directory is uniquely identified using its distinguished name (DN). A client application can choose to bind to the directory using an identity (DN and password) or anonymously. The C# code snippet below shows how to bind a user entry to an LDAP server:

Anonymous Binding

// C# Library namespace
using Novell.Directory.Ldap;

// Creating an LdapConnection instance 
LdapConnection ldapConn= new LdapConnection();

//Connect function will create a socket connection to the server
ldapConn.Connect (ldapHost,ldapPort);

//Bind function with null user dn and password value will perform anonymous bind to LDAP server 
ldapConn.Bind (null, null);

Binding Using an Identity

// C# Library namespace
using Novell.Directory.Ldap;

// Creating an LdapConnection instance 
LdapConnection ldapConn= new LdapConnection();

//Connect function will create a socket connection to the server
ldapConn.Connect(ldapHost,ldapPort);

//Bind function will Bind the user object Credentials to the Server
ldapConn.Bind(userDN,userPasswd);
