Need to fix No WS-Security header found issue

Hai All,

I am using wcf service to export an userdefined object. In that i am using

sample code :
objSender = new TimeCardV13_Async_OutClient("HTTPS_StartPeoplePort_SAP");
if (objSender.ClientCredentials != null)
{
objSender.ClientCredentials.UserName.UserName = UtilityLayer.Common.ObtainConfig("FMSStartUserName");
objSender.ClientCredentials.UserName.Password = UtilityLayer.Common.ObtainConfig("FMSStartPassword");
}
objSender.Open();

after crossing this, i get error. No WS-Security header found issue. may i know how to overcome this issue

If i need to include token. how should i do in ClientCredentials


Thanks in Advance
