Connect to Default Domain Controller with the LDAP Component

The LDAP component can connect using the current user's credentials by setting the authentication mechanism to Negotiate and calling Bind, eliminating the need to explicitly specify server or user credentials.

After binding, you can perform a simple search to retrieve the default distinguished name (DN), which can be used for subsequent operations.

// Tell the component to use the default Domain Controller as the server
ldap1.Config("UseDefaultDC=true");
// Specify the Negotiate mechanism so the current users credentials can be used with NTLM/Negotiate 
ldap1.AuthMechanism = LdapAuthMechanisms.amNegotiate;
ldap1.Bind();
// After binding search the root to find the default DN
ldap1.DN = "";
ldap1.SearchScope = LdapSearchScopes.ssBaseObject;
ldap1.Search("objectClass=*");
string defaultDN = ldap1.Attr("defaultNamingContext");

Additionally, the component can be used to query the default domain controller at any time:

Console.WriteLine(ldap1.Config("DomainController"));

This method provides a convenient way to establish a connection to Active Directory using the current user context without requiring manual configuration of connection details.
