How to enable Windows Authentication in WCF service?

When we create a WCF service application, it also has a web.config file associated with it. So open the web.config file and ensure that the authentication mode is Windows. The third step is to define the bindings and the transport type. To define the bindings, we need to enter the basicHttpBinding element inside the bindings XML tag.

Are there authentication mechanisms in Windows Communication Foundation?

The following topics show a number of different mechanisms in Windows Communication Foundation (WCF) that provide authentication, for example, Windows authentication, X.509 certificates, and user name and passwords.

How to secure a service with Windows Authentication?

The following scenario shows a Windows Communication Foundation (WCF) client and service secured by Windows security. For more information about programming, see How to: Secure a Service with Windows Credentials. An intranet Web service displays human resources information. The client is a Windows Form application.

How to set securitymode for integratedwindowsauthentication?

The authentication schemes configured on the host (‘IntegratedWindowsAuthentication’) do not allow those configured on the binding ‘BasicHttpBinding’ (‘Anonymous’). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly.

How does Windows Communication Foundation ( WCF ) work?

Windows Communication Foundation (WCF) allows you to create a service that exposes a Web endpoint. Web endpoints send data by XML or JSON, there is no SOAP envelope. This topic demonstrates how to expose such an endpoint.

The following scenario shows a Windows Communication Foundation (WCF) client and service secured by Windows security. For more information about programming, see How to: Secure a Service with Windows Credentials. An intranet Web service displays human resources information. The client is a Windows Form application.

How to create a basic WCF Web HTTP service?

To host the service Create a WebServiceHost object. WebServiceHost host = new WebServiceHost(typeof(Service), new Uri(“http://localhost:8000/”)); Dim host As WebServiceHost = New WebServiceHost(GetType(Service), New Uri(“http://localhost:8000/”)) Add a ServiceEndpoint with the WebHttpBehavior.

The authentication schemes configured on the host (‘IntegratedWindowsAuthentication’) do not allow those configured on the binding ‘BasicHttpBinding’ (‘Anonymous’). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly.

How to specify client credential values in WCF?

Create an instance of the WCF client using the generated code. On the client class, set the ClientCredentials property of the ClientBase<TChannel> class to an appropriate value. This example sets the property to an X.509 certificate using the SetCertificate method of the X509CertificateInitiatorClientCredential class.

How does WCF check authenticity of a message?

Signed: WCF ensures that message has come only from authenticated caller. WCF checks validity of message by checking Checksum at service side. It provides authenticity of message. Encrypted & Signed: Message is signed as well as encrypted. It provides integrity, privacy and authenticity of message.

When does IIs ask the client to authenticate itself?

When IIS asks the client to authenticate itself, the browser sends a token that represents the Windows account of the current user. Technically, this authentication incorporates two authentication mechanisms, NTLM and Kerberos.

How to pass client credentials to WCF service?

The setting of client credentials has obviously changed in the WCF world. Does anyone know how I can replicate the old ASMX behaviour of setting the DefaultCredentials in a WSHTTP WCF service? Thanks for any help.

If the service is running under a different account, Windows Communication Foundation (WCF) generates a UPN in the form of < username >@< domainName >. This occurs because Kerberos authentication requires that a UPN or SPN be supplied to the client to authenticate the service.

Signed: WCF ensures that message has come only from authenticated caller. WCF checks validity of message by checking Checksum at service side. It provides authenticity of message. Encrypted & Signed: Message is signed as well as encrypted. It provides integrity, privacy and authenticity of message.
