The WindowsClientCredential enables the setting of Windows client properties used when communicating with a service. The AllowedImpersonationLevel sets the level of impersonation the service can assume when impersonating the client. The ClientCredential enables a client to authenticate with username and password to the service. The AllowNtlm determines whether NTLM can be used to authenticate the client if Kerberos is not used.

The following example creates a client and gets a reference to the WindowsClientCredential. The code then changes the AllowedImpersonationLevel to a new value.

// Create a service host.
EndpointAddress ea = new EndpointAddress("http://localhost/Calculator");
WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);
b.Security.Message.ClientCredentialType = MessageCredentialType.Windows;

// Create a client. The code is not shown here. See the WCF samples 
// for an example of the CalculatorClient code.

CalculatorClient cc = new CalculatorClient(b, ea);
// Get a reference to the Windows client credential object.
WindowsClientCredential winCred= cc.ClientCredentials.Windows;
Console.WriteLine("AllowedImpersonationLevel: {0}", 
    winCred.AllowedImpersonationLevel);
Console.WriteLine("AllowNtlm: {0}", winCred.AllowNtlm);
Console.WriteLine("Domain: {0}", winCred.ClientCredential.Domain);

Console.ReadLine();
// Change the AllowedImpersonationLevel.
winCred.AllowedImpersonationLevel = 
    System.Security.Principal.TokenImpersonationLevel.Impersonation;

Console.WriteLine("Changed AllowedImpersonationLevel: {0}", 
    winCred.AllowedImpersonationLevel);
Console.ReadLine();
// Open the calculator and use it. 
//cc.Open(); 
//Console.WriteLine(cc.Add(11, 11)); 

//// Close the client. 
//cc.Close();
