Get claims for service using Windows validation

Question

I have the following code which was validation using username & password. How can I use Windows credentials instead?
private static SecurityToken GetClaims(string serviceurl, string username, string password)
bool isincurrentusercontext = String.IsNullOrEmpty(username);
WS2007HttpBinding binding = new WS2007HttpBinding();
binding.Security.Mode = SecurityMode.TransportWithMessageCredential;
binding.Security.Message.EstablishSecurityContext = false;
EndpointAddress endpoint = new EndpointAddress(new Uri(GetStsUrl(isincurrentusercontext)));
WSTrustChannelFactory trustChannelFactory;
if (!isincurrentusercontext)
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
trustChannelFactory = new WSTrustChannelFactory(binding, endpoint);
trustChannelFactory.Credentials.UserName.UserName = username;
trustChannelFactory.Credentials.UserName.Password = password;
else
trustChannelFactory = new WSTrustChannelFactory(new KerberosWSTrustBinding(SecurityMode.TransportWithMessageCredential), endpoint);
trustChannelFactory.TrustVersion = TrustVersion.WSTrust13;
trustChannelFactory.Credentials.UseIdentityConfiguration = true;
WSTrustChannel channel = null;
RequestSecurityToken rst = new RequestSecurityToken(RequestTypes.Issue);
rst.AppliesTo = new EndpointReference(serviceurl);
rst.KeyType = KeyTypes.Bearer;
channel = (WSTrustChannel)trustChannelFactory.CreateChannel();
SecurityToken token = channel.Issue(rst);
((IChannel)channel).Close();
channel = null;
trustChannelFactory.Close();
trustChannelFactory = null;
return token;
If I change credential type from username to Windows,
binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;
and remove these two statements,
trustChannelFactory.Credentials.UserName.UserName = username;
trustChannelFactory.Credentials.UserName.Password = password;
and when i try to get the token, 
SecurityToken token = channel.Issue(rst);
I get the following error,
"Secure
channel cannot be opened because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly specified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or
implied by the EndpointAddress correctly identifies the remote endpoint"

Hi,
For Client configuration, in order for the service-client communication to work we need to specify the security type and the ClientCredentialType. These settings must match the security settings in the service.
