HTTP_SERVER_AUTHENTICATION_INFO structure (http.h)

The HTTP_SERVER_AUTHENTICATION_INFO structure is used to enable server-side authentication on a URL group or server session. This structure is also used to query the existing authentication schemes enabled for a URL group or server session.

This structure must be used when setting or querying the HttpServerAuthenticationProperty on a URL group, or server session.

Syntax

typedef struct _HTTP_SERVER_AUTHENTICATION_INFO {
  HTTP_PROPERTY_FLAGS                      Flags;
  ULONG                                    AuthSchemes;
  BOOLEAN                                  ReceiveMutualAuth;
  BOOLEAN                                  ReceiveContextHandle;
  BOOLEAN                                  DisableNTLMCredentialCaching;
  UCHAR                                    ExFlags;
  HTTP_SERVER_AUTHENTICATION_DIGEST_PARAMS DigestParams;
  HTTP_SERVER_AUTHENTICATION_BASIC_PARAMS  BasicParams;

Members

Flags

The HTTP_PROPERTY_FLAGS structure that specifies if the property is present.

AuthSchemes

The supported authentication schemes. This can be one or more of the following:

Authentication Scheme	Meaning
HTTP_AUTH_ENABLE_BASIC	Basic authentication is enabled.
HTTP_AUTH_ENABLE_DIGEST	Digest authentication is enabled.
HTTP_AUTH_ENABLE_NTLM	NTLM authentication is enabled.
HTTP_AUTH_ENABLE_NEGOTIATE	Negotiate authentication is enabled.
HTTP_AUTH_ENABLE_KERBEROS	Kerberos authentication is enabled.
HTTP_AUTH_ENABLE_ALL	All types of authentication are enabled.

ReceiveMutualAuth

A Boolean value that indicates, if True, that the client application receives the server credentials for mutual authentication with the authenticated request. If False, the client application does not receive the credentials.

Be aware that this option is set for all requests served by the associated request queue.

ReceiveContextHandle

A Boolean value that indicates, if True, that the finalized client context is serialized and passed to the application with the request. If False, the application does not receive the context. This handle can be used to query context attributes.

DisableNTLMCredentialCaching

A Boolean value that indicates, if True, that the NTLM credentials are not cached. If False, the default behavior is preserved.

By default, HTTP caches the client context for Keep Alive (KA) connections for the NTLM scheme if the request did not originate from a proxy.

ExFlags

Optional authentication flags. Can be one or more of the following possible values:

Value	Meaning
HTTP_AUTH_EX_FLAG_ENABLE_KERBEROS_CREDENTIAL_CACHING	If set, the Kerberos authentication credentials are cached. Kerberos or Negotiate authentication must be enabled by AuthSchemes.
HTTP_AUTH_EX_FLAG_CAPTURE_CREDENTIAL	If set, the HTTP Server API captures the caller's credentials and uses them for Kerberos or Negotiate authentication. Kerberos or Negotiate authentication must be enabled by AuthSchemes.

DigestParams

The HTTP_SERVER_AUTHENTICATION_DIGEST_PARAMS structure that provides the domain and realm for the digest challenge.

BasicParams

The HTTP_SERVER_AUTHENTICATION_BASIC_PARAMS structure that provides the realm for the basic challenge.

Remarks

The HTTP_SERVER_AUTHENTICATION_INFO structure is included in the HTTP request if authentication has been configured on the associated URL group. The original HTTP authentication header received from the client is always included in the HTTP request, regardless of the authentication status.

Requirements

Requirement	Value
Minimum supported client	Windows Vista [desktop apps only]
Minimum supported server	Windows Server 2008 [desktop apps only]
Header	http.h
