WS_HTTP_HEADER_AUTH_SECURITY_BINDING structure (webservices.h)

  • Article

The security binding subtype for specifying the use of HTTP header authentication against a target service or a HTTP proxy server based on the basic, digest (RFC 2617) and the SPNEGO (RFC4559) protocols. Since this security binding operates at the HTTP header level, it is supported only with the WS_HTTP_CHANNEL_BINDING. By default, this security binding is used for the target service. However WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_TARGET security binding property can be specified to use it for a HTTP proxy server. This binding provides client authentication, but not message protection since the HTTP body is unaffected by this binding. While this security binding can be used alone, such usage is not recommended; more typically, HTTP header authentication is done in conjunction with transport level security provided by a security binding such as the WS_SSL_TRANSPORT_SECURITY_BINDING. To use this binding without SSL, the security description property WS_SECURITY_PROPERTY_TRANSPORT_PROTECTION_LEVEL must be explicitly set to WS_PROTECTION_LEVEL_NONE.

With this security binding, the following security binding properties may be specified:

Syntax

typedef struct _WS_HTTP_HEADER_AUTH_SECURITY_BINDING {
  WS_SECURITY_BINDING                   binding;
  WS_WINDOWS_INTEGRATED_AUTH_CREDENTIAL *clientCredential;
} WS_HTTP_HEADER_AUTH_SECURITY_BINDING;

Members

binding

The base type from which this security binding subtype and all other security binding subtypes derive.

clientCredential

The Windows Integrated Authentication credential to be used to authenticate the client. This is required on the client side and must be NULL on the server side.

If the credential used is a WS_DEFAULT_WINDOWS_INTEGRATED_AUTH_CREDENTIAL then WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_SCHEME must be set to WS_HTTP_HEADER_AUTH_SCHEME_NONE, WS_HTTP_HEADER_AUTH_SCHEME_NTLM, WS_HTTP_HEADER_AUTH_SCHEME_NEGOTIATE or WS_HTTP_HEADER_AUTH_SCHEME_PASSPORT. WS_HTTP_HEADER_AUTH_SCHEME_PASSPORT defaults to using the Passport keyring.
