WCF Client can not understand CRMOD Administrative Service response

Dear All,

I'm trying to integrate CRM OD with custom application and I need to access administrative services API. These services only support stateless access. I can send the request sucessfully and service also responded to the request but my WCF client is not able to understand the response and raise an exception. I got the following message:

The header 'Security' from the namespace 'http://docs.oasis-open.org/wss/2004/01

/oasis-200401-wss-wssecurity-secext-1.0.xsd' was not understood by the recipient

of this message, causing the message to not be processed.  This error typically

indicates that the sender of this message has enabled a communication protocol
