How can i Send response to authorize client?

Just finished my first WCF service.

I want to limit the client to get service from my WCF serv开发者_开发百科er - so i want to response just to client that have the right password ( password will send as string in one of the argument field ) or just response to client that have specific ip address.

How can i do it in WCF ?

Thanks for any help.

The "normal" expected behavior would be for the WCF service to:

• return a valid result for those users who are authorized to call that service
• throw a FaultException (possibly a typed FaultException<SecurityNegotiationException>) for those users who are not authorized
