Question

I am trying to access my WCF service on a server from my client console application for testing   I am getting the following error       The caller was not authenticated by   the service   I am using wsHttpBinding   I m not sure what kind of authentication the service is expecting                                                                                            lt behaviors gt     lt serviceBehaviors gt       lt behavior name  MyTrakerService MyTrakerServiceBehavior  gt         lt  -- To avoid disclosing metadata information  set the value below to false and remove the metadata endpoint above before deployment -- gt         lt serviceMetadata httpGetEnabled  true   gt         lt  -- To receive exception details in faults for debugging purposes  set the value below to true   Set to false before deployment to avoid disclosing exception information -- gt         lt serviceDebug includeExceptionDetailInFaults  false   gt       lt  behavior gt     lt  serviceBehaviors gt   lt  behaviors gt      Update It works if I change my binding to  lt endpoint   basicHttpBinding        gt   from wsHttpBinding  on the IIS 7 0 hosted  windows 2008 server

Have you tried using basicHttpBinding instead of wsHttpBinding  If do not need any authentication and the Ws-  implementations are not required  you d probably be better off with plain old basicHttpBinding  WsHttpBinding implements WS-Security for message security and authentication

Why can t you just remove the security setting altogether for wsHttpBinding   none  instead of  message  or  transport

If you re using a self hosted site like me  the way to avoid this problem  as described above  is to stipulate on both the host and client side that the wsHttpBinding security mode   NONE    When creating the binding  both on the client and the host  you can use this code     Dim binding as System ServiceModel WSHttpBinding   binding  New System ServiceModel WSHttpBinding System ServiceModel SecurityMode None    or   System ServiceModel WSHttpBinding binding  binding   new System ServiceModel WSHttpBinding System ServiceModel SecurityMode None

if needed to specify domain which authecticates username and password that client uses  in webconfig you can put this in system serviceModel services service  section    lt identity gt             lt servicePrincipalName value  example com    gt   lt  identity gt    and in client specify domain and username and password    client ClientCredentials Windows ClientCredential Domain    example com    client ClientCredentials Windows ClientCredential UserName    UserName     client ClientCredentials Windows ClientCredential Password    Password

This can be caused if the client is in a different domain than the server   I encountered this when testing one of my applications from my PC client  to my  cloud  testing server and the simplest solution i could think of was setting up a vpn

I also had the same problem in wsHtppBinding  And I just had to add security mode pointing to none  that solved my problem and no need to switch to basicHttpBinding  Check Here and check how to disable WCF security   Check the below config change for reference    lt wsHttpBinding gt       lt binding name  soapBinding  gt           lt security mode  None  gt               lt transport clientCredentialType  None    gt               lt message establishSecurityContext  false    gt           lt  security gt       lt  binding gt   lt  wsHttpBinding gt
