WCF - wsHttpBinding with UserName Autentication and Message - error message "An error occurred when processing the security tokens in the message"

I'm trying to create WCF applications with username authentication. And this error occurring.

This is the service configuration:

</configuration>

Class Autentication

namespace Jsl.BureauInf.Security
{
public class Autenticacao : UserNamePasswordValidator
{
    public override void Validate(string userName, string password)
    {
        if (userName != "yaron")
            throw new SecurityTokenException("Unknown Username or Password");
    }
}
}

Client

    BureauService.TransportadoraClient service = new BureauService.TransportadoraClient();
    service.ClientCredentials.UserName.UserName = "xxx";
    service.ClientCredentials.UserName.Password = "xxx";
    service.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;

    BureauService.RESPOSTADTC rep = service.ConsultarTransportadora(consulta);

When the client makes request for service triggers the following error:

InnerException.Message: An error occurred when processing the security tokens in the message.

Message: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.

What should I do to fix this error?

This response can happen for a several reasons. The two that I suspect the most are:

1. You are sending the incorrect client credentials to the server. I see you are sending a UserName and Password as "xxx". However, your server is expecting a UserName of "yaron". This is the expected response from the server in that case.

2. The client machine has an invalid time or one that is more than 5 minutes different from the server. The default MaxClockSkew value for the WSHttpBinding is 5 minutes.
